Nutrients : chemicals needed for growth & maintenance of life ex . , fe nutrients get recycled - not like energy 1 comes from outside of earth) Nutrient cycles : can be described as terms of pools. Where nutrients are stored fluxes - movement in and out of pools input v5. output carbon : essential nutrient required for growth & reproduction. Basic building block of organic molecules carbon is stored in oceans & atmosphere /main reservoirs) also important pools : soil , living organisms , and fossil fuels carbon enters plants through capturing co2 during photosynthesisincorporated into organic molecules. 6 co2 + 6420 co hiz 06 + 602 ] not. _ testable light sugar cellular respiration carbon enters animals by being passed along food chain by consumers. Reservoirs carbon returns to the atmosphere by being released by living organisms during cellular respiration. Humans emit carbon-based greenhouse gases to the atmosphere through deforestation & fossil fuel use.
