Community✔✔members of different species participate in a number of ecological
interactions
Community Structure✔✔is affected by the number, composition, and relative
abundance of different species within a community.
Foundation Species✔✔Species that are large or abundant
Competition✔✔negatively affects both organisms involved
Exploitation✔✔benefits one organism while harming the other
Positive interactions✔✔benefit one or both organisms without harming either
Disturbances✔✔can affect a community by removing organisms or altering resource
availability. Examples- Marine Heat Waves, Storms, Human Activities
Competitive Exclusion✔✔local elimination of the inferior competitor—can result
when two species use the same limited resources.
Interspecific interactions✔✔are any interactions that occur between individuals of
different species.
Ecological niche✔✔is the specific set of biotic and abiotic environmental resources it
uses.
Two species cannot coexist permanently in a community if their __________ are
identical.✔✔Niches
Resource partitioning✔✔is the differentiation of niches that enables similar species
to coexist in a community.
Niche differentiation✔✔competing species in a community use their environment
differently to better coexist
Fundamental Niche✔✔is the niche potentially occupied by that species.
Realized Niche✔✔is the portion of the fundamental niche actually occupied by that
species.
Exploitation✔✔refers to any +/- interaction in which individuals of one species benefit
by feeding on individuals of the other species
Predation✔✔(+/-) refers to an interaction in which an individual of one species—the
predator—kills and eats an individual of another species—the prey.
