lecture 29 - interactions between organisms including mutualism Flashcards
types of interactions
intra-specific (within species)
inter-specific (among species)
what is competition
interaction where different individuals/species compete for a limited resource
what is mutualism
an ecological interaction between two species in which both benefit
what is commensalism
an ecological relationship in which one species benefits while the other isn’t harmed or helped in any significant way
what is amensalism
competition with no effect on winning competitor
what is parasitism
relationship in which a parasite eats the cell contents, tissue or bodily fluids of its host
what is symbiosis
2 animals living together
what is a niche
the specific set of biotic and abiotic resources that an organism uses in its environment
what is the fundamental ecological niche concept
no two species can have identical ecological niches
what is a realised niche
the set of factors used by a species when other organisms are in the environment
how can species avoid competition
by partitioning their niche
what is obligate mutualism
where one species cannot survive without the other
what is facultative mutualism
where both species can survive independently
