Document Summary

Any chemical required for the proper functioning of organisms. Macronutrients are required by living organisms in large quantities. Includes the transfer, chemical transformation and recycling of nutrients in ecosystems. The end-products and by-products of one system are sources of food and essential nutrients for another. Transfers of material between compartments such as soil, air, or the biosphere biosphere. Quantitative estimate of the rates of nutrient input and output to and from an ecosystem and within the system. The time which quantities of nutrients remain in compartments reservoirs. Compartments that release their nutrients faster than they release them. Vast quantities of carbon are transferred from one to another. Weather of carbon minerals and combustion of fossil fuels. Metalimnion - middle, depth which temperature decreases rapidly. Hypolimnion - deep, cold portion of the lake. *temperature cools in fall - uniform temperature called isothermal. The wind is only capable of making the epilimnion.
