Apes’ unit 3 test for exam Review

3 Levels of biodiversity genetic: measure of genetic variation of individuals in a population (smallest level of biodiversity, the larger the pop = larger genetic diversity, more diverse has better chance at adapting, precondition for evolution by natural selection) species: # of species in a defined area (most common) ecosystem (habitat): variety of dif habitats, communities, and ecological processes; largest scale (natural prairies, forests. rivers, lakes) why each level of biodiversity is important genetic: improves long term health/survival, helps species adapt to change, resistance against diseases, loss is danger bc food supply would go down species: more habitats = more species ecosystem: increased species diversity = more productive and resilient ecosystem, better able to recover from nat disasters, critical indicator of envi health
