Components of biodiversity

Question 1

What are the 3 types of diveristy

Answer 1

Genetic, species, ecosystem

Question 2

What is genetic diversity?

Answer 2

Number and frequency of all the alleles in a population.

Question 3

What is the effect of a population dying out on genetic diversity?

Answer 3

species may have lost some of its genetic diversity, and this may limit its ability to evolve successfully by adapting to changing environmental conditions

Question 4

What is species diveristy?

Answer 4

Species diversity comprises the number of different species in an ecosystem (the species richness) and the proportion of each species in the ecosystem (the relative abundance)

Question 5

What is species richness?

Answer 5

the number of different species in an ecosystem

Question 6

What is the relative species abundance?

Answer 6

the proportion of each species in the ecosystem

Question 7

How does having a dominant species affect species diversity?

Answer 7

Because species diversity is dependent upon both the species richness and their relative abundance, a community with a dominant species will have a lower species diversity than one with the same species richness but no particularly dominant species.

Question 8

What is ecosystem diversity?

Answer 8

the number of distinct ecosystems within a defined area
