Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. 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.

A food chain is a linear sequence of organisms through which nutrients and energy pass from one organism to another through consumption. 2)The food web are species are the nodes of the network or the links in the chain: to survive, they obtain energy from those that are at a lower level.  3)tropic webs are interconnected and are a more realistic representation of consumption relationships in ecosystems
