Question	Answer
What are the two types of interspecific competition? Define them.	Resource competition: When resource is in limited supply Interference competition: When there is direct harm to an individual
Why does resource competition occur?	Niche overlap
What is a niche?	Set of resources that can be used by a species
What happens to the range of a species when competition arises?	Range decreases
What is the theory of limiting similarity?	Two species with identical niches cannot coexist indefinitely.
