Which of the following is a sign of a healthy ecosystem?

High biodiversity and stable populations are key indicators of a healthy ecosystem. Biodiversity refers to the variety of life forms within a given habitat or ecosystem, encompassing different species of plants, animals, fungi, and microorganisms. A diverse ecosystem is more resilient, meaning it can better withstand challenges like diseases, climate change, and invasive species. Each species plays a unique role, contributing to the overall functioning of the ecosystem, such as pollination, nutrient cycling, and food web dynamics.

Stable populations suggest that the species within the ecosystem are not facing significant threats that could lead to their decline or extinction. When populations are stable, it indicates that the ecosystem can support its inhabitants and that the environmental conditions are suitable for a range of life forms. Together, high biodiversity and stable populations create a more balanced and robust ecosystem, allowing it to thrive and maintain ecological processes.
