Explanation:

Question 1

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

Natural resources are materials that occur in nature. Coal is a fossil fuel from nature, sunlight is a natural energy source. Plastic is a man - made material, not a natural resource.

Renewable resources can be replenished, non - renewable cannot be replenished quickly. Wind is renewable, fresh water can be renewed (through cycles), oil is a fossil fuel and is non - renewable as it takes millions of years to form.

Answer:

C. both living and nonliving things.
