Explanation:

Question 1

The environment includes all components of an ecosystem, which has biotic (living) and abiotic (non - living) factors. So it contains both.

Natural resources are from nature. Coal and sunlight are natural, but plastic is man - made, so it's not a natural resource.

Wind is renewable, fresh water can be renewed (e.g., through the water cycle), but oil is a fossil fuel formed over millions of years and is non - renewable.

Answer:

C. both living and nonliving things.
