Document Summary

March 15: competition, contest for limited resource. Ie: light (plants compete for light, habitat (example. Where species build nests: water, food, organisms compete for access to mate, soil nutrients, plants compete for mates with pollinators, shelter. Intraspecific competition: member of species use the same limited resource, negatively influencing population growth rates and population size, reduce instantaneous birth rate. Interspecific competition: two species use the same limited resource, negatively influencing each other"s population growth rates and population sizes, reduce instantaneous birth rate. Increase death rates: uses the logistic growth model (demonstrates competition within species, type of competition, exploitation. Individuals depress each other"s birth rates (or increase death rates) through the use of a shared limited resource: compete by using up the resource first, also called resource competition. Individuals depress each other"s birth rates (or increase death rates) by doing things that reduce the exploitation efficiency the other individual.
