Habitat – place where organism lives and obtains its energy Need to compete to get the most resources from your habitat Need to develop special characteristics or strategies to beat everyone else

Competition – struggle between organisms to survive in a habitat with limited resources Adaptation – behaviors and physical characteristics of organisms that allow them to survive in their environment

And the Winner is… Adaptations come from random mutations Animal doesn ’ t plan something, but a behavior or physical characteristic gives them an advantage over others E.g. Cheetah Natural Selection – process in which individuals that are better adapted to environment are more likely to survive and reproduce

Predation – interaction when one organism kills and eats another Predator – killer organism Prey – organism that is killed Predator adaptations: Cheetah – speed Jellyfish – stinging tentacles Pitcher plant – rotting smell Prey adaptations: Protective coverings Toxins Warning colors (red, orange) Camouflage – hide well Mimicry – look like something else False Coloring - eyespots

Food chain – series of events when one organism eats another and obtains energy
