Components Of Biodiversity Flashcards
Examples of components of biodiversity
• Genetic diversity
• Species diversity
• Ecosystem diversity
What is genetic diversity?
Genetic diversity is the number and frequency of all the alleles within a population.
What happens when one population of a species dies out?
If one population of a species dies out then the species may have lost some of its genetic diversity and will limit its ability to adapt to changing conditions.
What is species diversity?
Species diversity comprises the number of different species in an ecosystem(species richness). And proportion of species in an ecosystem(relative abundance).
What happens in a community with a dominant species?
Has a lower species diversity than the one with the same species richness but no particularly dominant species.
What is ecosystem diversity
Ecosystem diversity refers to the number of distinct ecosystems within a defined area.
