Test 3 SCI 225What is an ecosystem? - correct answer a community of organism interacting with each other and their physical environment (biotic and abiotic) What is a community? - correct answer multiple species of organisms interacting with each other (biotic) what is a population? - correct answer one species What is species richness - correct answer the count, or total number of unique species within a given biological community, ecosystem, biome, or other defined area what is spe...

population - ANSWER an interbreeding (sharing genetic information) group of individuals who live in the same geographic area and exist at the same time variability within a species/population (importance) - ANSWER important because: -some genetic variations have advantages over others -natural selection can act on the variation that arises What if populations are separated and can't exchange genes? - ANSWER two processes can occur: 1. genetic divergence 2. speciation genetic diverg...
