Isabel Torres, p.4 20.03.17 1. Biotic part means the living part of the nutrient cycle, any part of the cycle where the nutrient is found within a living organism. Abiotic means the non-living part of the nutrient cycle, any part of the cycle where the nutrient is present as an inorganic molecule. a. Nutrients move from the abiotic to the biotic part when they are absorbed and assimilated by producers. Carbon dioxide (abiotic/inorganic) is fixed during photosynthesis into glucose (biotic/organic) 2. Within the biotic part of the cycle, nutrients move by feeding -- they move through the food chain when consumers eat the producers. a. Nutrients are found in rocks, sediments, dissolved in water (in soil or in rivers, lakes, and oceans) and in the atmosphere during the abiotic part of the cycle. 3. Upwelling increases the nutrients available to the phytoplankton and therefore increases the rate of photosynthesis. Productivity increases and there is more food for the consumers. So, the numbers of both producers and consumers

    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.
