What are the components of environment?

The basic components of the environment are atmosphere or the air, lithosphere or the rocks and soil, hydrosphere or the water, and the living component of the environment or the biosphere.

BIOTIC COMPONENTS (LIVING) : It consists of the living parts of the environment, including the association of a lot of interrelated populations that belong to different species inhabiting a common environment. The populations are those of the animal community, the plant community and the microbial community. BIOTIC COMPONENTS (LIVING) consists of the living parts of the environment, including the association of a lot of interrelated populations that belong to different species inhabiting a common environment.

The biotic community is divided into:

  1. Autotrophs,
  2. Saprotrophs, and
  3. Heterotrophs

ABIOTIC COMPONENTS (NON-LIVING) : these are the most important determining factor of where and how well an organism exists in the environment. Although these factors interact with each other, one single factor can limit the range of an organism thus acting as the limiting factor.

These factors can be categorized into following groups: PHYSICAL FACTORS: the major components are temperature, Water (Rainfall), Light (Energy), Soil, Atmospheric pressure. INORGANIC AND ORGANIC SUBSTANCES : – Water, Oxygen, Carbon, Nitrogen, Sulphur, Nitrates, Phosphates and ions of various metals etc. are inorganic substances essential Education Is Which Type Of Components Of Our Environment

How many types of environment components are there?

Four Components of Environment – The four major components of environment include lithosphere, hydrosphere, atmosphere and biosphere, corresponding to rocks, water, air and life respectively.

Lithosphere is the outermost layer of earth called crust, which is made of different minerals. Its depth can reach up to 100 kilometers and is found on both land (terrestrial crust) and oceans (oceanic crust). The main component of lithosphere is earth’s tectonic plates. Hydrosphere comprises of all forms of water bodies on earth including oceans, seas, rivers, lakes, ponds, streams etc. It covers 70% of earth’s surface.97.5% of water found on Earth is in the oceans in the form of salt water. Only 2.5 % of water on Earth is freshwater. Out of this, 30.8% is available as groundwater and 68.9% is in frozen forms as in glaciers. Amount of 0.3% is available in rivers, reservoirs and lakes and is easily accessible to man. Atmosphere is gaseous layer enveloping the Earth. The atmosphere with oxygen in abundance is unique to Earth and sustains life. It mainly comprises 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and traces of hydrogen, helium, and noble gases. The amount of water vapour present is variable. Biosphere refers to all the regions on Earth where life exists. The ecosystems that support life could be in soil, air, water or land. The term Biosphere was coined by Geologist Edward Suess who used this term for place on Earth where life can be found. Biosphere refers to the sum total of all living matter, the biomass or biota. It extends from the polar ice caps to the equator, with each region harboring some life form suitable to the conditions there.

Environmental science is an interdisciplinary subject. It draws from a whole gamut of subjects like geography, geology, biology, chemistry, physics, botany, zoology, genetics, sociology, rural development, urban planning, policy development, politics, cultural studies, economics, ethics, law, education, health, communication and philosophy.

What are types of environments?

Aquatic, terrestrial, and atmospheric – Based on the components, the environment may also be classified into (1) aquatic environment (marine, such as oceans and seas, and freshwaters, such as lakes and rivers), (2) terrestrial environment (land), and (3) atmospheric environment (air).

  1. Marine environments are the largest known environments, they are characterized by the presence of water with great salt content.
  2. On the other hand, freshwater environments have less salt content.
  3. Marine environments represent about 97% of the water on Earth.
  4. Organisms within marine environments communicate with each other and with their physical surrounding.

These environments are of great importance to humans because it is an important source of nutrition and resources. Marine pollution, acidification, and warming are threats to the marine environment as a result of human activities.

Credit: Photo by DAVID ILIFF, CC BY-SA 3.0, Terrestrial environments are environments found on land only. It represents the land of islands and continents and organisms living on them.

Unlike aquatic or marine environments, terrestrial environments are not abundant in water; therefore, the presence of water in terrestrial environments is important. Due to the relatively lower availability of water, the temperature of terrestrial environments fluctuates daily and seasonally. There are six terrestrial ecosystems: taiga, rainforests, temperate forests, tundra, deserts, and grassland.

The atmospheric environment refers to the atmospheric component of an environment. The atmosphere (air) is a part of the Earth that has a huge impact on the thriving and survival of many organisms. Solar radiation, air components, climate, and air pollution are just some of the physicochemical attributes that can define an environment.

  1. Living organisms have adapted to living in a particular environment with its specific conditions, such as humidity, temperature, light, and so on.
  2. All these factors affect the species in the environment.
  3. Therefore, living organisms have to adapt and modify through time to survive and tolerate different environmental conditions.

Nevertheless, the environment itself also ‘evolves’. For example, oxygen eventually became incorporated into the Earth’s atmosphere after being released by photosynthetic organisms (such as algae ) when producing sugar as food. Oxygen, eventually, became indispensable to the thriving of aerobic organisms, such as animals, including humans.

Different environments are found around us — from the natural to the artificial, Artificial (or “built”) environments are affected fully or partially by human technology. They include urban settings, parks, buildings, and neighborhoods containing all water, energy, and roads where people can live and work.

The meaning of the natural environment is that this type of environment occurs in nature and not made by man. In a natural environment, vegetation, for instance, would grow by itself without being introduced or cultivated artificially.

    What is the basic component of biosphere?

    Read a brief summary of this topic – biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

    • Before the coming of life, Earth was a bleak place, a rocky globe with shallow seas and a thin band of gases—largely carbon dioxide, carbon monoxide, molecular nitrogen, hydrogen sulfide, and water vapour.
    • It was a hostile and barren planet.
    • This strictly inorganic state of Earth is called the geosphere; it consists of the lithosphere (the rock and soil), the hydrosphere (the water), and the atmosphere (the air).

    Energy from the Sun relentlessly bombarded the surface of the primitive Earth, and in time—millions of years—chemical and physical actions produced the first evidence of life: formless, jellylike blobs that could collect energy from the environment and produce more of their own kind.

    • This generation of life in the thin outer layer of the geosphere established what is called the biosphere, the “zone of life,” an energy-diverting skin that uses the matter of Earth to make living substance.
    • The biosphere is a system characterized by the continuous cycling of matter and an accompanying flow of solar energy in which certain large molecules and cells are self-reproducing.

    Water is a major predisposing factor, for all life depends on it. The elements carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, when combined as proteins, lipids, carbohydrates, and nucleic acids, provide the building blocks, the fuel, and the direction for the creation of life.

    • Energy flow is required to maintain the structure of organisms by the formation and splitting of phosphate bonds.
    • Organisms are cellular in nature and always contain some sort of enclosing membrane structure, and all have nucleic acids that store and transmit genetic information.
    • All life on Earth depends ultimately upon green plants, as well as upon water.

    Plants utilize sunlight in a process called photosynthesis to produce the food upon which animals feed and to provide, as a by-product, oxygen, which most animals require for respiration. At first, the oceans and the lands were teeming with large numbers of a few kinds of simple single-celled organisms, but slowly plants and animals of increasing complexity evolved.

    1. Interrelationships developed so that certain plants grew in association with certain other plants, and animals associated with the plants and with one another to form communities of organisms, including those of forests, grasslands, deserts, dunes, bogs, rivers, and lakes.
    2. Living communities and their nonliving environment are inseparably interrelated and constantly interact upon each other.

    For convenience, any segment of the landscape that includes the biotic and abiotic components is called an ecosystem, A lake is an ecosystem when it is considered in totality as not just water but also nutrients, climate, and all of the life contained within it.

    • A given forest, meadow, or river is likewise an ecosystem.
    • One ecosystem grades into another along zones termed ecotones, where a mixture of plant and animal species from the two ecosystems occurs.
    • A forest considered as an ecosystem is not simply a stand of trees but is a complex of soil, air, and water, of climate and minerals, of bacteria, viruses, fungi, grasses, herbs, and trees, of insects, reptiles, amphibians, birds, and mammals.

    Stated another way, the abiotic, or nonliving, portion of each ecosystem in the biosphere includes the flow of energy, nutrients, water, and gases and the concentrations of organic and inorganic substances in the environment. The biotic, or living, portion includes three general categories of organisms based on their methods of acquiring energy: the primary producers, largely green plants; the consumers, which include all the animals; and the decomposers, which include the microorganisms that break down the remains of plants and animals into simpler components for recycling in the biosphere.

    • Aquatic ecosystems are those involving marine environments and freshwater environments on the land.
    • Terrestrial ecosystems are those based on major vegetational types, such as forest, grassland, desert, and tundra,
    • Particular kinds of animals are associated with each such plant province.
    • Ecosystems may be further subdivided into smaller biotic units called communities,

    Examples of communities include the organisms in a stand of pine trees, on a coral reef, and in a cave, a valley, a lake, or a stream. The major consideration in the community is the living component, the organisms; the abiotic factors of the environment are excluded.

In a stand of pines, there may be many species of insects, of birds, of mammals, each a separate breeding unit but each dependent on the others for its continued existence.

    A species, furthermore, is composed of individuals, single functioning units identifiable as organisms. Beyond this level, the units of the biosphere are those of the organism: organ systems composed of organs, organs of tissues, tissues of cells, cells of molecules, and molecules of atomic elements and energy.

    The progression, therefore, proceeding upward from atoms and energy, is toward fewer units, larger and more complex in pattern, at each successive level. This article focuses on the makeup of the biosphere and examines the relationships between its principal components, including man, The characteristics and dynamics of biological populations and communities are dealt with, as are the interactions that constitute the primary stabilizing links among the constituent organisms.

    Due attention is also given to the distribution patterns of these biotic units and to the processes that produced such patterns. The major aquatic and terrestrial ecosystems of Earth are treated in some detail. Other points include energy transformations and transfers within the biosphere and the cyclic flow of materials needed for life.
