What is a key characteristic of ecosystems with high biodiversity?

Ecosystems with high biodiversity are characterized by greater stability and resilience, which means they are better equipped to withstand environmental changes and stressors. This stability arises because a diverse array of species can fulfill different ecological roles, ensuring that essential functions—such as nutrient cycling, pollination, and decomposition—remain intact even when certain species decline or are lost.

High biodiversity creates a network of interactions that can buffer the ecosystem against disturbances, such as natural disasters or human activities. For example, if one species is negatively impacted by a change in the environment, other species can often compensate, maintaining the overall functionality of the ecosystem.

In contrast, ecosystems that lack diversity may rely heavily on a few key species, making them more vulnerable to collapse if those species are affected by disease, climate change, or other threats. Thus, the presence of a wide variety of species contributes significantly to the overall health and resilience of ecosystems.
