Explain Why Scientists Believe That Warm Climates Provide Greater Biodiversity.

Which statement best exemplifies the biodiversity of an ecosystem?

A. A small pond has about 1,300 organisms and 26 different species living in it.

Which statement best describes how biodiversity supports the sustainability of an ecosystem?

D. Maintaining diversity ensures that species can continue to depend on one another.

Which factors tend to promote higher biodiversity in an ecosystem? Check all that apply.

B. diversity of niches
D. large area
E. warm climate

Explain why scientists believe that warm climates provide greater biodiversity.

Sample Response: Warm climates allow for a year-round growing season. Plants are more available as a food resource, which can support more organisms.
