Question

the diversity of ecosystems plays what role in the stability of the biosphere? the diversity of species makes the biosphere less stable. the diversity of ecosystems plays no role in the stability of the biosphere. the diversity of ecosystems helps maintain a stable biosphere.

Explanation:

In ecology, ecosystem diversity contributes to the biosphere's stability. More diverse ecosystems mean more functional redundancy, resilience to disturbances (like climate change or species loss), and better nutrient cycling, energy flow, etc. The first option is wrong (diversity usually increases stability), the second is wrong (ecosystem diversity does impact biosphere stability). The third option aligns with ecological principles: diverse ecosystems support stable biosphere processes.

Answer:

The diversity of ecosystems helps maintain a stable biosphere.
