Explanation:

In ecology, species can be classified into two main niche categories. A generalist species has a broad niche and can tolerate a wide range of conditions and use a variety of resources. A specialist species has a narrow niche and is adapted to specific conditions and resources. The terms "cool and tepid" relate to temperature and not ecological niches. "Amateur and professional" are human - related terms and not relevant to species niches.

Answer:

generalist and specialist
