3.7 Components of Biodiversity Flashcards
1
Q
What is genetic diversity?
A
The number and frequency of all the alleles within a population
2
Q
What is species diversity?
A
The number and proportion of each species in an ecosystem
3
Q
What is ecosystem diversity?
A
Ecosystem diversity refers to the number of distinct ecosystems within a defined area
4
Q
What are the properties of an ecosystem with a dominant species?
A
A community with a dominant species has a lower species diversity than one with the same species richness but no particularly dominant species
5
Q
What happens if one species of a population dies out?
A
The species may have lost some of its genetic diversity and this may limit its ability to adapt to changing conditions
