Explain how each interaction affects the survival and reproductive success of the two species involved. State the competitive exclusion principle. Define an ecological niche and restate the competitive exclusion principle using the niche concept. Explain how interspecific competition may lead to resource partitioning.

Describe how predators may use mimicry to obtain prey. Give specific examples of adaptations of herbivores. Distinguish among endoparasites, ectoparasites, and parisitoids. Distinguish among parasitism, mutualism, and commensalism. Explain why it is difficult to classify a symbiotic relationship as commensal. Community Structure Explain the relationship between species richness and relative abundance and explain how both contribute to species diversity. Distinguish between a food chain and a food web. Describe two ways to simplify food webs. Summarize two hypotheses that explain why food chains are relatively short. Explain the experimental evidence that supports the energetic hypothesis. Explain how dominant and keystone species exert strong control on community structure. Describe an example of each. Explain how a foundation species may facilitate the survival and reproduction of other species. Distinguish between the bottom-up and top-down models of community organization. Describe the successful biomanipulation of Finlands Lake Vesijrvi. Disturbance and Community Structure Define stability and disturbance. Describe the intermediate disturbance hypothesis. Explain why moderate levels of disturbance may create conditions that foster greater species diversity than low or high levels of disturbance. Distinguish between primary and secondary succession. Describe how species that arrive early in succession may facilitate, inhibit, or tolerate later arrivals. Describe the biotic and abiotic changes that have occurred during primary succession on glacier moraines in Glacier Bay, Alaska. Describe an example of humans acting as agents of disturbance. Biogeographic Factors Affect Community Biodiversity Explain why species richness declines along an equatorial-polar gradient.
