Which of the following is true about ecosystems with high biodiversity?

Ecosystems with high biodiversity are characterized by a wide variety of species interacting within their environment, which contributes significantly to their overall stability and productivity. Greater biodiversity often means that ecosystems can better withstand environmental changes and disturbances, such as climate variations, natural disasters, or human impacts.

The presence of multiple species allows for various ecological niches to be filled, leading to complex interrelationships that enhance resilience. For instance, if a particular species is affected by disease or environmental change, other species may fill its role, preventing a breakdown in ecosystem function. Moreover, diverse ecosystems can utilize resources more efficiently, leading to higher productivity, whether in terms of biomass, nutrient cycling, or energy flow.

In summary, the robustness provided by a variety of species supports both stability, which refers to the ability to maintain structure and function over time, and productivity, indicating the efficiency of energy and resource use within the ecosystem.
