An oxidizing agent is a substance, which causes another element or compound to go from a lower to a higher oxidation state. An example is found when oxygen combines with iron to form rust. Top P Photosynthesis is the process by which plants form carbohydrates from carbon dioxide and water, mediated by sunlight on chlorophyll. Phycobilins are red and blue pigments found in blue-green and red algae. Phycoerythrin is the red pigment found in red algae.
Phytoplankton are microscopic plants that are free floating in the open water.
Phytoplankton biomass is the weight of the living phytoplankton in a given area. Potable water is water that is suitable to drink. In an aqueous solution, it can refer to the settling out of a substance due to a chemical reaction or a state of supersaturation. Pyrite oxidation is the chemical reaction that occurs between oxygen and pyrite. Pyrite, commonly known as fool's gold, is widely distributed in rock of all ages and is used chiefly as a source of sulfur for sulfuric acid.
