Plankton

Plankton is a collection of microscopic animals and plant organisms that live in the water column of the open part of the world's oceans, as well as in fresh waters. It makes up more than 90% of all inhabitants of the world's oceans and serves as an important link in marine ecosystems. The microscopic size of plankton determines its properties and characteristics, which determine a very important role in the ocean biosphere.

Plankton is a collection of various flora and fauna organisms that inhabit the water column and maintain their lifestyle based on the active movement of water masses. It is usually divided into several types: phytoplankton, which reproduces vegetatively using the processes of photosynthesis, with active movement in water under light conditions. Zooplankton reproduce sexually and live in the upper and middle layers of the water column, feeding and relying on prey. This simplest classification
