Adaptations to get food
Predator and Prey Adaptations
Genetic Bottleneck
Insecticide resistance
Four parts of Natural Selection
When a population decreases quickly to only a few members, genetic variation decreases. Can lead to diseases and birth defects.
Insects develop resistance to the insecticide. Crops are not protected and get ruined by insects. Kills crops. European corn borer
Overpopulation Genetic Variation Struggle to survive Successful reproduction
Cactus- very deep roots in the desert Chameleon - long, very fast tongue Birds have different shaped and size of beaks to get food in their biome (habitat).
Defense against predators: Camouflage (Chameleon, Alligator) Protective Armor (turtle, porcupine, cactus) Chemical warfare (skunk) Mimicry (non venomous snakes "look" like the very deadly coral snake). Spider webs are traps
