Which term describes the variety of living organisms and habitats in a given area?

  1. Species richness

  2. Evolution

  3. Migration

  4. Biodiversity

The correct answer is: Biodiversity

Explanation Biodiversity is the term used to describe the variety of living organisms and habitats in a given area. This includes all living organisms such as plants, animals, and microorganisms, as well as their interactions with each other and their environment. Species richness, while related to biodiversity, only refers to the number of different species in a given area. Evolution is the process by which species change over time, and migration is the movement of organisms from one place to another. While both of these concepts are important for understanding biodiversity, they are not the best term to describe the full scope of diversity in a given area. Therefore, D, biodiversity, is the correct answer.
