Document Summary
Types of interactions: antagonistic = one benefits, one is harmed. Niche: niche-the set of physical and biological conditions a species requires for survival, growth, and reproduction, ex. Tautoga evolved with the hard shell of mussels to crack them open. A predator is fast, strong, sharp claws, teeth; they have some characteristic that helps them. The prey have evolved strategies to help them escape, such as big eyes, ears, and high rate of reproduction; they also can have cryptic coloration (camo) Predation affects community structure if predators are too efficient, not only is prey exterminated, but predators will also go extinct. A way prey can protect itself is poisions. Poision dart frogs, skin has compounds that are toxic to larger animals. Doing this has a drawback, because the predator has to eat them first, then it kills them. Prey is still killed, even if predator is too. However, the point is, overtime, the predator learns to avoid the bright colored one.
