Community is a group of populations of different species living close enough to _____. Community interactions can be classified by whether they ____, ___, or have no effect on the species involved.
Community is a group of populations of different species living close enough to interact. Community interactions can be classified by whether they help, harm, or have no effect on the species involved.
Ecological niche - _______ of species’ use of the _______ and abiotic _______ in its environment
In other words, if their niches are compatible to each other and to the ecological niche, they can coexist and not compete.
Ecological niche - sum of species’ use of the biotic and abiotic resources in its environment
In other words, if their niches are compatible to each other and to the ecological niche, they can coexist and not compete.
________ - Individuals from the same species compete for a limited resource (population ecology)
Intraspecific - Individuals from the same species compete for a limited resource (population ecology)
_______ - individuals from different species compete for a limited resource(community ecology)
Interspecific - individuals from different species compete for a limited resource(community ecology)
competitive exclusion
Two species ________ for same limiting resources cannot coexist permanently in same place, one will be outcompeted
Two species competing for same limiting resources cannot coexist permanently in same place, one will be outcompeted
If __________ competition is high it can reduce interspecific competition
If intraspecific competition is high it can reduce interspecific competition
Species can ______ by shifting to a different resource (_________) or partitioning the same resource across space or time
Species can coexist by shifting to a different resource (competitive displacement) or partitioning the same resource across space or time
Competition can be a _________which leads to character displacement and drives evolution
Competition can be a selective pressure which leads to character displacement and drives evolution
_________ is any phenomena which alters the behavior and fitness of living organisms within a given environment.
Selective pressure is any phenomena which alters the behavior and fitness of living organisms within a given environment.
