Living Things React

You and all organisms live an environment. An environment is made up of everything that surrounds an organism.
An organism responds to changes in its environment. When an organism responds to a change, it reacts in certain ways. All living things respond in some way.
Have you ever noticed how plants and insects respond to light? Plants bend toward light. Insects fly toward light.
You respond to your environment in many ways, too. You may shiver if you are cold. What other ways do you respond to changes in your environment?
