I gave my students this multiple choice question: How does the buying and selling of a popular species of rainforest animal as pets have a negative effect on the rainforest ecosystem?

Only one answer is correct among these 4 choices:
- The rate of photosynthesis may decrease.
- There is a probability of genetic variability.
- The number of symbiotic relationships increases.
- It could lead to the potential extinction of those animals.

Could you tell me which one is correct?

It could lead to the potential extinction of those animals.
