Phosphorus is a major constituent of nucleic acids, phospholipids, and atp. phosphate (po4 3–) is the most important inorganic form of phosphorus. the largest reservoirs are sedimentary rocks of marine origin, the oceans, and organisms. phosphate binds with soil particles, and movement is often localized.

Title: ecosystems and restoration ecology 1 chapter 55 ecosystems and restoration ecology 2 overview. an ecosystem consists of all the organisms living in a community, as well as the abiotic factors with which they interact ; ecosystems range from a microcosm, such as an aquarium, to a large area such as a lake or forest. Restoration ecology • it is an iterative process: • 1) examines preexisting, historic, and current reference conditions prior to designing the plan • 2) developing a restoration plan • 3) obtain permits, do the work • 4) implementing plan, although complex (e.g. hydrology, soil, plant & animal responses) • 5) monitoring the site. Definition of ecosystem restoration: ‘the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed’. , there are many approaches to restoration, and the choice of approach should arguably be based on – 1. which is most appropriate given the objectives. 2. which provides the greatest likelihood of.
