What Is the Environment?

Every organism, or living thing, lives in an environment. An organism’s environment includes everything that surrounds it. Air, water, sunlight, and soil are all part of the environment. The environment provides each organism with everything it needs to live.

All over Earth there are many different kinds of plants and animals that are specially suited to live in their environments. However, the environment can sometimes be harmful to the organisms that are part of it. No matter how different each environment is, they all have one thing in common. They are always changing. Plants and animals must react to these changes in order to survive.
