, Populations - CORRECT ANSWER-abundance/distribution patterns of groups
of organisms: processes of birth, death and migration
-Evolutionary change occurs at the population level (interactions between

Communities - CORRECT ANSWER-Interactions between MULTIPLE
populations of different spp.
-Energy, nutrient and chemical pathways (ecosystem ecology)
Conservation ecology - CORRECT ANSWER-Blend of evolution, population,
community, and ecosystem ecology
The 4 myths of evolution - CORRECT ANSWER-1. mutations do not generally
transform an individual that is already alive
2. Mutations are inherited from parents to offspring
3. Evolution typically leads to alternative not ultimate forms
4. Evolution requires a selection pressure
