Unit 2 Flashcards
What are the three types of biodiversity?
- Ecosystem Diversity: The diversity of habitats an ecosystem has
- Species Diversity: The amount of different species that exist in an ecosystem.
- Gene Diversity: For a given population (group of the same species), how diverse the genepool is.
What are the two types of species diversity?
- Species Richness: How many species
- Species eveness: How even the populations of the species are spread out
Why is biodiversity important?
The amount of diversity in an exosystem allows it to be more resilient to population-disrupting events.
Define:
Bottleneck Event
An event that disrupts an ecosystem by eliminating a large amount of the population
Why are bottleneck events important?
When a population dereases by a lot, so does the biodiversity. Even though the population will increase, the biodiversity is still lower which does makes the environment less resistent.
Define:
Inbreeding Depression
When organisms are reproducing with organisms that are very closely related to each other leading to genetic defects
