- A realized niche describes the conditions of the environment in which a species is actually found, while a fundamental niche describes the potential environmental conditions tolerated by a species. True FalseContrast the concept of fundamental vs. realized nicheWhen species occupy the same niche, they must compete with each other for limited resources. Check each outcome that is likely to occur in the long-term if two species occupy the same niche. (Select all that apply): O Exclusion of one species from the entire niche, but not the other. OExclusion of both species from the entire niche. Persistence of both species throughout the entire niche. O Division of the niche into two smaller niches, each dominated by a single species. Alternating cycles where one of two species is initially excluded but subsequently becomes dominant, excluding the other.
- Describe “niche.”The competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.K P Parchment Exchange - Leader i edgenuity.com/player/ - SC5181 A 7 1 X Unmark this question + 7 8 What would happen to the ecosystem services provided by a coral reef if it were to sustain permanent damage? O The water that would otherwise filter through the coral polyps would become more dense with plankton. O There would be higher concentration of water pollution that could harm other organisms.
