The term for the variety of species in a given habitat is species richness. Species richness is a key component of biodiversity and is often measured by counting the number of different species present in a specific area. High species richness typically indicates a healthy ecosystem, as it enhances stability, resilience, and productivity. Conversely, low species richness can signal ecological distress or degradation. Understanding species richness is vital for conservation efforts, as it aids in assessing ecosystem health and guiding management practices.
