Most plants and animals live in areas with very specific climate conditions. For example, temperature and rainfall patterns determine what resources are available for organisms to survive in their environment. Any change in the climate of a region can affect the region's plants and animals, as well as the makeup of the entire ecosystem.
How does biodiversity affect an ecosystem's ability to stabilize when its climate changes?
A.
Ecosystems with low biodiversity are more stable because they are able to absorb the pressures of a changing climate.
B.
Ecosystems with low biodiversity are less stable because there are too many species for the ecosystem to support.
C.
Ecosystems with high biodiversity are more stable because they are able to absorb the pressures of a changing climate.
D.
Ecosystems with high biodiversity are less stable because there are too many species for the ecosystem to support.
