9251569291	community	A group of various species that live in the same habitat and interact with each other	0
9251569292	commensalism	A relationship between two organisms of different species where one benefits and the other is neither harmed nor benefited	1
9251569293	habitat	type of environment in which a species typically lives	2
9251569294	symbiosis	A relationship in which two different organisms live in close association with each other	3
9251569295	mutualism	A relationship between two species in which both species benefit	4
9251569297	competitive exclusion	process whereby two species compete for a limiting resource, and one drives the other to local extinction	5
9251569298	ecological niche	the resources and environmental conditions that a species requires	6
9251569299	interspecific competition	competition between members of different species	7
9251569300	resource partitioning	species adapt to access different portions of a limited resource; allows species with similar needs to coexist	8
9251569303	parasitism	relationship in which one species withdraws nutrients from another species, without immediately killing it	9
9251569305	pioneer species	species that colonize a new habitat	10
9251569306	primary succession	An ecological succession that begins in an area where no biotic community previously existed	11
9251569307	secondary succession	Succession following a disturbance that destroys a community without destroying the soil	12
9251569310	keystone species	A species that influences the survival of many other species in an ecosystem	13
