Answer 2

Deer

Step-by-step explanation:

A biotic factor is something that is living. For example, a plant or an animal is a biotic factor.

Water, sunlight and soil are not alive. They are all examples for abiotic factors, or things that aren't living.

Deer are animals and they are alive. Therefore, the biotic factor is a deer.
