In order for phytoplankton to use it, it must be nitrogen-fixedated by cyanobacteria where it's turned into nitrates- phytoplankton use the broken down nitrates.

<h3>Phytoplankton uses nitrate for what purposes?</h3>

The presence or absence of nutrients in the water, like phosphate and nitrate, affects the amount of phytoplankton in the water.Phosphorus and nitrate, which are markers of the quality and quantity of water fertility, are crucial for the growth & metabolism of phytoplankton, according to .
