What are two ways in which predation can affect a community (one immediate term, one is evolutionary) 4. Define competition. Know the difference between inter -and intra- specific competition. 5. What are two ways in which competition can affect a community? (same as above for predation) 6. What does competitive exclusion mean? When is it likely to occur? 7. What is one evolutionary response to intense interspecific competition? 8. What does mutualism mean? 9. Recognize the examples given in class. 10. What is a community?
