1. Why is diversity important in maintaining the stability of an ecosystem? 2. What is the broadest level of ecological classification within the biosphere?
What are the major abiotic factors used to characterize them?
3. What is the importance of plants in the ecosystem?

That’s why biodiversity is important to ecosystems because it protects the environment from extreme conditions. Even if some species fail to survive, others will remain to sustain the ecosystem and the living things.
