Final Study Guide . 1 . Define what is a fundamental versus realized niche: function of a particular species in an ecological community (Refer to page 1193) A niche is everything about the organism, Phenotype multidimendional. Activity periods Nests/ burrows (microhabitat) Habitat Soil Mating, How? When? Where? Reproduction ( how many?) Fundamental niche – Includes resources an organism theoretically could use. Realized niche – is the niche which is being forced to occupy, due to competition. Is the resources it actually does use determined by competition, predation, absence of a potential resource. -The situation with the Barnacle study restricted the same species that competed with the same habitat. -Gausse - No same species can occupy the same niche for an extended time, one species will be eliminated. 3. What is competition ? Which species would have the highest levels of interspecific Competition in a community? Competition interactions in which two organisms use the same resources and those resources are insufficient to supply their combined needs ( -/- interaction). The species that have the highest levels of interspecific competition would be species that share prey. Another example is the Barnacles. Competition may restrict species habitat use. Gausse theory can be applied. 5 . What are the trophic levels of heterotrophs ? Give an example of each. What is a detrivore, decomposer ? Trophic levels of heterotrophs consist of the organisms whose energy source has passed through the same number of steps to reach them.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
