It will destroy the fish habitat. It will provide nutrients to algae. It will change the water temperature. It will introduce an invasive species.
I gave my students this multiple choice question: A scientist observed that the loss of plants near a stream resulted in more soil being washed downstream. How will the excess soil that travels downstream reduce biodiversity?

Only one answer is correct among these 4 choices:
- It will destroy the fish habitat.
- It will provide nutrients to algae.
- It will change the water temperature.
- It will introduce an invasive species.

Could you tell me which one is correct?

It will destroy the fish habitat.
