Energy Pyramid: -10 % rule: only 10% of energy is passed to the next trophic level -90% lost: heat, non assimilated-waste, respiration, some of it not digested or completely eaten-and is lost in waste/feces -not being cycled, it is a one way flow Biomass: total mass of organic matter: -producers have most -pyramid of numbers: most are producers, then primary consumers have second most, etc. -exception to rule: inverted pyramid -Ex? oak tree-one organism, then a lot of insects live there, etc. -definition of decomposers, recycling that stuff Carbon Cycle: dynamics of ecosystem: -know reservoir and form -atmosphere, CO2 -atmosphere into food chain-photosynthesized by producers -return to reservoir=respiration or combustion -Nitrogen: N2 atmosphere, nitrogen fixation by bacteria, denitrifying bacteria

    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.
