Phytoplankton

Aquatic Ecosystems, HIPM Entities

Overview

Phytoplankton are photosynthesizing microscopic organisms that inhabit the upper sunlit layer of almost all oceans and bodies of fresh water. They are agents for "primary production," the creation of organic compounds from carbon dioxide dissolved in the water, a process that sustains the aquatic food web.

-- Phytoplankton (WP)

Photoinhibition is light-induced reduction in the photosynthetic capacity of a plant, alga, or cyanobacterium.

-- Photoinhibition (WP)

Phytoplankton grow in the presence of Nutrients (eg, Iron, Nitrate) Phytoplankton suffer various forms of Death. In particular, they are subject to Grazing by Zooplankton.
