In terms of biodiversity, what indicates a healthy ecosystem?

A healthy ecosystem is characterized by a high number of species and genetic diversity. This abundance and variety of organisms contribute to ecosystem resilience, stability, and functionality. Biodiversity allows ecosystems to better withstand environmental changes and disturbances, such as diseases, climate shifts, or human impacts.

Having many species ensures various roles within the ecosystem, promoting complex interactions that sustain ecological balance. Genetic diversity within species is equally important because it enables populations to adapt over time to changing circumstances, enhancing survival prospects.

In contrast, a low variety of organisms may indicate a lack of resilience, while uniformity in species traits can lead to vulnerability if environmental conditions change. Limited food options typically reflect a narrowed food web and can detrimentally impact the health and sustainability of an ecosystem. Overall, the richness in species and the variety of genetic traits foster robust ecosystems capable of thriving under a range of conditions.
