1 COMMUNITY ECOLOGY II PP

2 PREDATION (+/-) one species eats another species
predator: eater and prey: eaten Types: carnivores, herbivores

3

4 cyclic in nature – ↑ in prey leads to ↑ in predators (vice versa)
PREY: SEA URCHINS PREDATOR: SEA STARS cyclic in nature – ↑ in prey leads to ↑ in predators (vice versa) Adaptations in prey for defense against predators

5 RESPONSES TO PREDATION
camouflage: Cryptic coloration disguises an animal so it’s less visible to predators or prey

6 warning coloration: intended not to camouflage an organism but to make it more noticeable
- Bright coloring, scent, or taste to warn potential aggressors

7

8 mimicry: physical (or behavioral resemblance) of one species to another
1. natural selection of a second moth species favors moths who look like the bad tasting species (bright colors) 2. color patterns may be similar

9 moment of truth defenses: action by prey just before death that is unexpected by predator

10 alluring coloration: animals are colored so a predator's attention is drawn to a non-vital part of the prey's body
