Phosphorus cycle By: Julissa Benitez, Nilda Ruiz, Stephanie Huerta, and Axel Miranda
The phosphorus cycle • The phosphorus cycle describes the movement of phosphorus through the geosphere, hydrosphere, and biosphere. • The phosphorus cycle reflects the balanced interactions between organisms and their biotic and abiotic environments. • Phosphorus flows through each compartment by give and receive actions and allowing life to exist.
The phosphorus cycle • An interesting fact about the phosphorus cycle is that there is no phosphorus in the atmosphere. • Also, there is little to no phosphorus in the lithosphere and biosphere.
Disadvantages and Causes • A high concentration of phosphorus is harmful and even considered pollution. • Excess phosphorus that collects in bodies of water leads to eutrophication. • The result is an overproduction of weeds, plankton, and especially algae, which “destroy” lakes.
Effects and victims • Eutrophication comes from too much human input of nitrogen and phosphorus. • It affects the quality of water and habitats. • It changes both animal and plant populations.
Effect on environment & society • Products cause oxygen to decrease quality of water and change; water is toxic and unable of being used as a habitat • Plant and animal populations changed due to large amount of nitrogen and phosphorus created • Plants and some animals, like fish, die due to toxic water and reduce population.
