Low oxygen levels encourage the growth of bacteria that destroy nitrate - a vital nutrient for the ocean's microscopic plants, or phytoplankton.
低含氧量导致细菌滋长，这些细菌会破坏硝酸盐——海洋微生物及浮游植物的重要营养物质之一。

Phytoplankton, like land plants, require nutrients such as nitrate, phosphate, silicate, and calcium at various levels depending on the species.
浮游植物与陆地植物一样，根据不同种类需要各级的硝酸盐、磷酸盐、硅酸盐以及钙等营养物质。

It was concluded that aerenchyma that formed in the root cortex impeded the radial transport of water in the root cylinder and decreased water uptake in water-stressed rice plants fed by nitrate.
