an increase in prey populations a decrease in prey populations a decrease in decomposers an increase in producers
I gave my students this multiple choice question: Which will most likely cause a decrease in predator populations?

Only one answer is correct among these 4 choices:
- an increase in prey populations
- a decrease in prey populations
- a decrease in decomposers
- an increase in producers

Could you tell me which one is correct?

a decrease in prey populations
