Document Summary
Different types of ecosystems may store nutrients in different compartments. Tropical forest very thin with small amount of nutrients in that component. Difference in amount of nutrients that are stored. Resident"s time: general amount of time that a particular molecule will spend in one storage compartment. Calculated by taking the overall amount of that particular storage pool, ratio. Carbon cycle) much shorter and sedimentary cycles (ex. phosphorus cycle) takes a lot longer. Important for developing root system, enhance stem strength and helping seeds to grow, speed up rate at which plants achieves maturity. Adding phosphorous to an ecosystem can help plants in numerous ways important component to develop bones and teeth (in humans and animals) Not stored as gas in the atmosphere but rather stored in rocks and sediment. Has to become available in some way, usually by weathering = tock breaks down into smaller pieces, these pieces make their way into the soil.
