I gave my students this multiple choice question: Which of these is the most serious impact to an ecosystem after a tornado?

Only one answer is correct among these 4 choices:
- an increase in biodiversity
- soil erosion along with water pollution
- the growth of plants in newly cleared areas
- animals relocating to different habitats

Could you tell me which one is correct?

soil erosion along with water pollution
