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 models accuracy when predicting the insect population size? decomposers recycling dead insects, annual variation in oxygen availability, activities of predators preying on insects, variation in barometric pressure

Explanation:

Predators directly impact insect population size. Decomposers recycling dead insects, annual variation in oxygen availability, and variation in barometric pressure have more indirect or less significant effects on the number of living insects compared to predation.

Answer:

C. activities of predators preying on insects
