Lesson Outline
Review the importance of nitrogen products to living organisms.
Discuss the nitrogen cycle from atmospheric nitrogen to usable nitrates through the action of nitrogen fixing bacteria and bacteria of decay.
Discuss the phosphate cycle from the weathering of rock and mining of phosphate rock for fertilizer to the organic phosphate products formed by assimilation.
List and examine the human impact on the phosphate cycle. Include the formation of algae bloom, the formation of dead zones in aquatic ecosystems, and the overuse of phosphate containing detergents causing overgrowth.
