There will be less water in the lake. More plants will grow in the lake. More frogs will live in the lake. There will be fewer insects in the lake.
I gave my students this multiple choice question: The number of fish in a lake suddenly increases. How will the increase most likely affect the lake?

Only one answer is correct among these 4 choices:
- There will be less water in the lake.
- More plants will grow in the lake.
- More frogs will live in the lake.
- There will be fewer insects in the lake.

Could you tell me which one is correct?

There will be fewer insects in the lake.
