Environment refers to the surrounding (both living
and non-living) of the livings species. The human-beings, plants,
animals and other living beings operate in the environment. Environment
is also sometimes referred to as habitat.
Environment consists of both living and non-living things. Living
things such as animals, plants, etc. interacts with both other living
and non-living things. Similarly, non-living things such as soil, water,
climate, temperature, sunlight, air, etc. interacts with other
non-living and living things.
There is a close relationship between living organisms and environment. Ecology is the branch of science that studies the interaction between organisms and their environment.
The interaction of living beings, including human-beings, brings
changes in the environment. Similarly, livings beings also display
changes within them with the change in the environment.
