Document Summary
Members of the same community compete for resources. Community ecology: the study of the suns of the abiotic and biotic factors that influence that influence birth/death rates, their interactions and their coexistence. Types of interspecific interaction: interactions that harm both species, interactions that benefit both species, interactions that harm one species but benefits another, some can have a neutral on one or both species. While interspecific interactions are considered at a species level, the actual harms/benefits are felt on an individual basis: can influence an individual"s fitness fitness then influences how a population evolves. Competition has a negative effect on all species involved in the interaction: Interspecific competition: competition between 2 or more species: determines how many individuals can live in a community, which species live in that community, influences individual fitness. Interference competition: when one species competes by directly interfering w/ another.
