Why is biodiversity important?

Biodiversity is crucial because it enhances ecosystem stability and provides a range of services that are essential for maintaining ecological balance. A diverse array of species within an ecosystem ensures that various ecological functions can be performed efficiently. This includes processes such as nutrient cycling, pollination, pest control, and water purification, all of which are vital for human survival and well-being.

Ecosystems with high biodiversity are generally more resilient to disturbances, such as climate change or natural disasters. This resilience arises because a variety of species can fulfill similar roles within the ecosystem; if one species is affected by a disease or environmental change, others may compensate, preventing significant disruptions to ecosystem functions. Therefore, biodiversity contributes not only to the stability of ecosystems but also to their ability to provide essential services that support life on Earth.

In contrast to the correct answer, the other options describe negative aspects such as complications in ecosystem management and decreases in resilience, which do not reflect the benefits that biodiversity brings. The idea that biodiversity reduces species competition is misleading, as diverse ecosystems often evolve mechanisms that allow multiple species to coexist and utilize different resources efficiently.
