Question

a sudden rise in a wolf population in a forest leads to a sharp decline in the local deer population due to overpredation. which type of factor contributed to the decline in the deer population? biotic factor of low food sources biotic factor of increased predation abiotic factor of decreased temperature ablotic factor of added unfavorable chemicals

Explanation:

Biotic factors are living - organism related factors in an ecosystem. Since the decline in deer population is due to increased predation by wolves (a living organism), it is a biotic factor of increased predation. Abiotic factors are non - living components like temperature or chemicals. The situation described does not involve low food sources but rather predation.

Answer:

biotic factor of increased predation
