PRODUCERS & CONSUMERS 3 What if a consumer is removed? If a consumer is removed from an ecosystem there is a real possibility that the next trophic level below will overpopulate. In what is called a trophic cascade, the effects of a predator cascade down the food web to the point where they have a direct effect on primary productivity. Plants for example can be controlled by a top-down method of control so that plant productivity is limited to demand of the ecosystem. How are the results different? The difference is that if a primary producer is removed the entire food chain will eventually collapse over time because energy decreases with each successive tropic level, or due to lack of essential energy. If you remove a consumer the lower trophic level will overpopulate and slowly begin to lose trophic efficiency. Overpopulation will occur choking off the next consumer’s ability to consume energy. In what situation would an ecosystem be unaffected by the removal of producer or consumer? An ecosystem functions as a unit of nature. The stability of the ecosystem depends on the species that inhabit it. The ecosystem contains producers, consumers, and decomposers all of which play a vital role. It is nearly impossible for an ecosystem to not be affected by the removal of a producer or a consumer (GlobalChange, 2008). Productivity, decomposition, energy flow, and nutrient cycling are important components that cannot be completed without the direct or indirect support from other species. The only way an ecosystem would not be affected is if another producer or consumer takes that species place and was able to function and contribute the same way as the absent species (GlobalChange, 2008).

    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.
