Leaves -> Caterpillar -> Bird Tree -> Bird -> Caterpillar Leaves -> Tree -> Caterpillar Caterpillar -> Leaves -> Bird
I gave my students this multiple choice question: Which diagram best shows how energy flows through a simple food chain?

Only one answer is correct among these 4 choices:
- Leaves -> Caterpillar -> Bird
- Tree -> Bird -> Caterpillar
- Leaves -> Tree -> Caterpillar
- Caterpillar -> Leaves -> Bird

Could you tell me which one is correct?

Leaves -> Caterpillar -> Bird
