What term describes the variety of life in a particular habitat or ecosystem?

The term that describes the variety of life in a particular habitat or ecosystem is biodiversity. Biodiversity encompasses all the different species, genetic variations, and ecological complexes within a specific environment. It reflects the complex interactions between organisms and their environments, contributing to the health and resilience of ecosystems. High biodiversity is often indicative of a stable and productive ecosystem, as it allows for more interactions and a broader range of responses to environmental changes.

Population refers to a group of individuals of the same species living in a specific area, while community denotes all the different species that interact in a particular location. Habitat diversity refers to the variety of habitats that exist within a certain area, which plays a role in supporting biodiversity but does not directly define it. Thus, biodiversity is the most comprehensive term for understanding the variety of life in a habitat or ecosystem.
