Document Summary
Intraspecific competition: between individuals of the same species (fighting for a mate) Interspecific: between two different species ex) lion and hyena vying for same meal. Exploitation competition: organisms compete with one another through consumption of a limiting resour(cid:272)e: the faster you eat the (cid:373)ore you get (cid:894)ru(cid:374)ts do(cid:374)"t sur(cid:448)i(cid:448)e(cid:895) or plants competing for water and nutrients. Interference competition: individuals compete directly with one another for resources: ex) eagles swoop in (can be physical intimidation) butting antlers, territoriality. Apparent competition: two species do not necessarily compete for the same resource but they do share at least one natural enemy. These organisms are specific to each other in the one particular area of or, presumably not all gardener snakes have the same level of resistance. Results show: competition can vary in at least three ways: presence of biotic factor (parasites) and abiotic factors (temperature and moisture)
