Phytoplankton Communities (Algae)

The mostly auto trophic branch of plankton, these communities are found throughout the ocean but especially abundant in the Neritic zone. Phytoplankton are influenced directly by nutrient availability, temperature, light distribution, bacteria, and parasites. Bird manuring also serves as a ready nitrogen source, making time to multiply faster. The majority of phytoplankton are photosynthetic, but a small percentage have replaced it with the ability to ingest food particles. They are usually 1mm at biggest, and many types have chloroplasts that are not green, providing easy basis for classification. One of the the most popular phytoplankton/algae are golden-brown and are classified as Bacillaviophyta. Other forms of phytoplankton are Dinophyta, Crysophta, Haptophyta, Xantopyta, Cryptophyta, Eustigmatopyta, Cyanophyta, Rhodophyta, and the green Clorophyta and Euglenophyta. Phytoplankton communities contribute to carbon that feeds zooplankton, which feed many fish, as well as proving the majority of Oxygen in the atmosphere, allowing humans and animals alike to live. Sea Urchins also feed on phytoplankton, and are a popular food choice among fish in the neritic zone. In other words, the phytoplankton communities would be considered among many as the most important community in the whole ocean.
