predator-prey competition for resources biotic factors interacting with each other energy transfer between producer and consumer
I gave my students this multiple choice question: In many tropical areas, mosquitoes may carry a parasite that can cause an infectious disease among humans. What best describes this type of relationship between mosquitoes and humans?

Only one answer is correct among these 4 choices:
- predator-prey
- competition for resources
- biotic factors interacting with each other
- energy transfer between producer and consumer

Could you tell me which one is correct?

biotic factors interacting with each other
