decomposers recycling dead insects annual variation in oxygen availability activities of predators preying on insects variation in barometric pressure
I gave my students this multiple choice question: A computer model of an insect population takes into account the following parameters: * available food resources * annual temperature variation * timing of insect reproductive cycles Which additional parameter would most significantly improve the model's accuracy when predicting the insect population size?

Only one answer is correct among these 4 choices:
- decomposers recycling dead insects
- annual variation in oxygen availability
- activities of predators preying on insects
- variation in barometric pressure

Could you tell me which one is correct?

activities of predators preying on insects
