The document provides an overview of key concepts in community ecology, including species interactions, trophic levels, food webs, succession, biomes, and factors that limit population growth. It defines important ecological terms and describes various types of species relationships, ecological roles, community changes over time, and Earth's major terrestrial biomes.

1. COMMUNITY ECOLOGY

10. Predation drives adaptations in prey Cryptic coloration : Camouflage to hide from predators Warning coloration : Bright colors warn that prey is toxic Mimicry : Fool predators (here, caterpillar mimics snake)

35. Fig. 3-11, p. 58 Zone of intolerance Optimum range Zone of physiological stress Zone of physiological stress Zone of intolerance Temperature Low High No organisms Few organisms Upper limit of tolerance Population size Abundance of organisms Few organisms No organisms Lower limit of tolerance

36. A: Represents the biotic potential of the species B: Shows how the population overshoots the carrying capacity C: Represents the logistic growth D: Represents linear growth E: Carrying capacity- the maximum number of individuals that can be supported by a particular ecosystem.

39. Secondary terrestrial succession
