Description about eBook : Phosphorus Cycle
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine tri-phosphate), DNA and    lipids (fats and oils). Insufficient phosphorus in the    soil can result in a decreased crop yield.
Here are the key steps of the phosphorus cycle,  Over time, rain and weathering cause rocks to release    phosphate ions and other minerals.  This inorganic phosphate is then distributed in soils    and water.  Plants take up inorganic phosphate from the soil. The    plants may then be consumed by animals. Once in the    plant or animal, the phosphate is incorporated    into organic molecules such as DNA. When the plant    or animal dies, it decays, and the organic phosphate is    returned to the soil.  Within the soil, organic forms of phosphate can be    made available to plants by bacteria that break    down organic matter to inorganic forms of    phosphorus. This process is known as mineralisation.  Phosphorus in soil can end up in waterways and    eventually oceans. Once there, it can be incorporated    into sediments over time.    Fig: The Phosphorus Cycle.............
