The earth consists of surroundings in which all living and non-living beings live their lives. The physical, biological, and natural forces of nature combine together and create circumstances that enable an organism to live. Such circumstances are called the environment. The French word ‘environ’ which means to surround is a derivative of the word environment.
All the biotic (living) and abiotic (non-living) entities constitute the environment. Biotic things include- humans, plants, animals, and insects. They are classified as biological components of the environment. Every biotic creature has its own fixed life-cycle. For example, human-being is the strongest living organism on earth. He needs plants and animals in order to fulfill his needs. His life-cycle will be disorganized without them.
Whereas, abiotic components involve atmosphere, lithosphere, hydrosphere, and biosphere. They are the layers of the environment. These layers are categorized as physical components of the environment. The atmosphere is the layer of air made up of nitrogen, oxygen, and other gases. All the water bodies such as rivers and oceans together make up the hydrosphere. The lithosphere is the solid, outermost part of the earth. It is made of crust that covers the mantle, rocks, and soil on the surface of the earth. The most important layer is the biosphere where life exists. It involves aquatic, terrestrial, and aerial ecosystems. From the root systems of trees to the deepest underwater life is what biosphere features.
The existence of all these organisms is dependent on their constant interaction with each other. Their functioning is organized by nature and can be destroyed once being squandered. Today, the degradation of the environment has become a major issue to be tackled by human beings.
The surroundings in which life exists on earth are called the environment. The environment contains air, water, sunlight, trees, animals, and human beings. They are the living and non-living creatures of the earth. The trees, human- beings, and animals are living organisms. The sun, water, and air are non-living organisms that are crucial for man’s survival. Every creature is a natural resource for each other. For example, deer is a natural resource to be eaten by a lion. Life on the earth would not be able to exist in the absence of any one of these natural resources.
However, the environment has components of the atmosphere and hydrosphere that influence the life of living beings. Gases such as nitrogen and oxygen are present in the atmosphere. Hydrosphere covers all the water bodies every living being is created according to the features of these components. For example, aquatic animals are created to breathe underwater. Aerial animals are made to breathe in air.
