System, ecosystem, ecology 2 important systems of biosphere A-hydrologic and carbon cycle Water Budget a- # of inflows/# of outflows of water in a given time b- Global water budget includes global average rates of evaporation, condensation, precipitation and evapotransportation c- Local water budget shows relationship between precipitation and evapotransportation- evaporationn into atmosphere and absorption(transpiration) by plants Water budget varies by season/vegetation cover. More vegetation= more evapotranspiration Carbon & Oxygen a- Atmospheric CO2 absorbed by plants carbohydrates via photosynthesis. b- Plants release oxygen back into atmosphere c- People and animals breather oxygen and return CO2 to atmosphere Lithosphere stores carbon via fossil fuels and carbon based rocks(limestone) Decomposing flower and animals release Carbon.

    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.
