Plants do not need minerals, and animals do. Plants produce their own food, and animals do not. Plants do not produce oxygen, and animals do. Plants need sunlight, and animals do not.
I gave my students this multiple choice question: What is one way plants and animals are different?

Only one answer is correct among these 4 choices:
- Plants do not need minerals, and animals do.
- Plants produce their own food, and animals do not.
- Plants do not produce oxygen, and animals do.
- Plants need sunlight, and animals do not.

Could you tell me which one is correct?

Plants produce their own food, and animals do not.
