Sentences with word «plankton»
Plankton refers to tiny organisms, like plants and animals, that live in bodies of water, such as oceans and lakes. They are so small that they cannot swim against the current and are carried along by the water. Plankton is an essential part of the ocean food chain, as many larger animals rely on them as a source of food. Full definition
