Questions and Answers

What is the difference between species composition and species diversity in a community?

Species composition is a listing of various species in the community, while species diversity includes both species richness and the relative abundance of the different species.

Provide an example of how community 1 and community 2 can have the same number of tree species but different species diversity.

Community 1 and 2 both contain 4 species of tree, but community 1 has greater species evenness, resulting in higher species diversity.

Explain how ecological niche differs from habitat.

Ecological niche refers to the role a species plays in its community, including its methods to meet energy, nutrient, and survival demands, while habitat refers to the specific place where a species lives and reproduces.
