1. Suggest reasons why the information represented in the pyramid of numbers of animals of one of the ecosystems you studied may not truly represent that ecosystem. The information represented in the pyramid of numbers of animals of one of the ecosystems I studied may not truly represent that ecosystem, because the ecosystem is changing every day so the numbers would also be changing. The numbers would also be estimated and not the true number of the animals in the ecosystem. 2. According to your data, what is the ratio of third-order consumers to producers? Explain your answer. The ratio of third-order consumers to producers is extremely low. Since energy is lost at every trophic level, when the energy reaches the third-order the energy level is low. There are usually fewer individuals at the top of the food chain than at the bottom. The ratio would usually be 1:100, because at each level 10% of the energy would be lost.

    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.
