a decrease in livable habitat a decrease in the normal temperature an increase in the amount of prey available an increase in the amount of competitors for food
I gave my students this multiple choice question: Which situation would affect an organism's niche in a positive way?

Only one answer is correct among these 4 choices:
- a decrease in livable habitat
- a decrease in the normal temperature
- an increase in the amount of prey available
- an increase in the amount of competitors for food

Could you tell me which one is correct?

an increase in the amount of prey available
