 Limiting factors  Resource in an environment is scarce…limits the amount of organisms in an eco system  Carrying capacity = total amount an ecosystem can support

 1. Competition = struggle with one another or the environment to survive  2. Predator/Prey = predator eats prey  Ex. Bird eats worm  3. Symbiosis = close relationship  Mutualism = both organisms benefit  Commensalism = one organisms benefits, the other is unaffected  Parasitism = one benefits, one is harmed  Ex. Parasite vs host

 mQE

 yU yU

 Habitat = environment in which an organism lives  Niche = organisms way of life with in an ecosystem

AAdaptations = change in… BBehavior PPhysical characteristics EEct. OOR AA characteristic that helps an organism to survive

 Examples  Viceroy = coloration/markings that mimic another organisms  Ex: A harmful organism (poisonous/undesirable) may mimic or act like another organism (i.e. monarch butterfly - harmless)  Camouflage = coloration to help blend in to surrounding
