c. biotic factors

Q1. a, Q2.b

Explanation:

Population is defined as a group of organisms living in an ecosystem. Hence the fox living in a forest ecosystem is a population.

Water , oxygen, carbon dioxide and light are the abiotic components in the environment. Whereas the organic matter such as cells, tissues and organisms are biotic components.

the correct answer is d
