The plankton can either be collected from a body of water or cultured, though the former method is seldom used. Phytoplankton is used as a foodstock for the production of rotifers, [62] which are in turn used to feed other organisms. Phytoplankton is also used to feed many varieties of aquacultured molluscs, including pearl oysters and giant clams.
Ancestors of Prochlorococcus contributed to the production of early atmospheric oxygen. [26] Despite Prochlorococcus being one of the smallest types of marine phytoplankton in the world's oceans, its substantial number make it responsible for a major part of the oceans', world's photosynthesis, and oxygen production.

This constant cycle of carbon through the system is not the only element being transferred. In animal and plant respiration these living beings take in glucose and oxygen while emitting energy, carbon dioxide, and water as waste. These constant cycles provide for a influx of oxygen into the system and carbon out of the system.
Aquatic Photosynthesis is the occurrence of photosynthesis in the aquatic environment, which includes the freshwater environment and the marine (saltwater) environment. . Organisms that perform photosynthesis in the aquatic environment include but are not limited to plants, algae, cyanobacteria, [1] coral, [2] phytoplankton (also known as micro al
Most (five out of six molecules) of the glyceraldehyde 3-phosphate produced are used to regenerate ribulose 1,5-bisphosphate so the process can continue. The triose phosphates not thus "recycled" often condense to form hexose phosphates, which ultimately yield sucrose , starch , and cellulose , as well as glucose and fructose .
It has been estimated that half of the world's oxygen is produced by phytoplankton. [7] [8] Larger autotrophs, such as the seagrasses and macroalgae are generally confined to the littoral zone and adjacent shallow waters, where they can attach to the underlying substrate but still be within the photic zone.
They break down complex organic compounds (e.g., carbohydrates, fats, and proteins) produced by autotrophs into simpler compounds (e.g., carbohydrates into glucose, fats into fatty acids and glycerol, and proteins into amino acids). They release the chemical energy of nutrient molecules by oxidizing carbon and hydrogen atoms from carbohydrates ...
Similar to plants, phytoplankton contain chlorophyll in their cells which act to capture sunlight, carbon dioxide, and water; These molecules are converted from light energy to chemical energy creating essential biomolecules like oxygen and glucose. Since phytoplankton have no use for the oxygen molecules, they are released and acquired by more ...
