Document Summary
In this chapter . : how elements are cycled in the biosphere, movement of water in water cycle, study the cycle of four elements that are important to organism, the effect of human activities on these cycles. Elements needed to carry out life function. Nutrients are components in foods that an organism uses to survive and grow. while micronutrients provide the necessary cofactors for metabolism to be carried out. Both types of nutrients can be acquired from the environment. Macronutrients provide the bulk energy an organism"s metabolic system needs to function. Required in relatively large amount: carbon, nitrogen, hydrogen, phosphorous, micronutrients. Required in very small amounts: manganese, boron. A pathway that a chemical follows as it cycles through the biota, soil, water, and the atmosphere: biosphere. Pools- part of ecosystem matter may reside (atmosphere, soil) Fluxes-rate of matter moves from one pool to another. Capital- total amount of element or molecule (mass)
