environmental issue unseen passage​

Answer 1

Answer:

Everything around us is environment. It refers to everything that surrounds and affects us. Our ecosystem is the community of living organisms and non-living components like air, water, soil and minerals. Environment includes atmosphere, vegetation, land, soil, natural phenomena, air, water, climate and all the natural resources etc.

Living elements such as animals, birds, plants etc are the biotic factors whereas the abiotic factors include water, air, sunlight etc. Biotic and abiotic factors interact and influence each other. The four spheres of environment are Atmosphere, Biosphere, Hydrosphere and Lithosphere. Besides natural environment, there is the man-made environment i.e. the areas in which man has transformed the land for personal use for urbanization and agricultural production, etc.
