I gave my students this multiple choice question: The living systems of plants and animals are constantly taking in water to continue the processes of life. What eventually happens to most of that water?

Only one answer is correct among these 4 choices:
- It is converted into hydrogen and oxygen.
- It is returned to the environment.
- It is broken down by bacterial decay.
- It is permanently combined with other compounds.

Could you tell me which one is correct?

It is returned to the environment.
