What is a major benefit of biodiversity in ecosystems?

A major benefit of biodiversity in ecosystems is that it enhances ecosystem resilience. This means that ecosystems with a wide variety of species are better able to withstand environmental stresses and recover from disturbances such as natural disasters, disease outbreaks, and climate change. A diverse set of species can fulfill different roles within an ecosystem, which contributes to its overall stability. For example, if one species is affected by a change in the environment, other species can adapt or take over the ecological functions previously performed by the affected species, thus maintaining the health and balance of the ecosystem.

Ecosystems with high biodiversity are less likely to suffer from collapse because they have a wide range of genetic diversity, species richness, and ecological interactions that can give them the flexibility needed to adapt to changes. This resilience is crucial for the long-term sustainability of ecosystems, ultimately benefiting all organisms, including humans, who rely on healthy ecosystems for resources such as clean air, water, and food.
