Which term refers to the variety of different habitats within an area?

  1. Biodiversity

  2. Population density

  3. Biome

  4. Habitat fragmentation

The correct answer is: Biodiversity

The correct term that refers to the variety of different habitats within an area is biodiversity. Biodiversity encompasses not only the variety of species within an environment but also the variety of ecosystems and habitats. This diversity is crucial for the resilience of ecosystems, as it contributes to their ability to adapt to changes and provides a greater range of services and resources. Population density refers to the number of individuals of a species within a specific area, which does not capture the complexity of various habitats. A biome is a large geographical area characterized by specific climate patterns and types of flora and fauna but does not focus on the variety of habitats within a smaller area. Habitat fragmentation describes the process by which a larger habitat is divided into smaller, isolated patches, which can impact biodiversity but does not define the concept of habitat variety itself.
