PREDATION (+/-)
• one species eats another species
• predator: eater and prey: eaten
• Types: carnivores, herbivores
• cyclic in nature – ↑ in prey leads to ↑ in predators (vice versa)
• Adaptations in prey for defense against predators
PREY: SEA URCHINS
PREDATOR: SEA
STARS
RESPONSES TO PREDATION
• camouflage: Cryptic coloration disguises an animal so it’s less visible to predators or prey
• warning coloration: intended not to camouflage an organism but to make it more noticeable
- Bright coloring, scent, or taste to warn
potential aggressors
• 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
