Question

How do planktons participate in the oxygen cycle?

Answer 1

Plankton lives in water and air and those species are unable to propel themselves against the wind. The specific species that contains the plankton are called plankters. Plankton is a vital food source for both small and large marine species in the seas, such as bivalves, fish and whales.

Complete answer:
The ocean generates oxygen by the plant phytoplankton and algal plankton that live in it. As a byproduct of photosynthesis, these plants generate oxygen, a mechanism that transforms carbon dioxide and sunlight into sugars that can be used by the organism for energy.
The oxygen cycle is a cycle that aims to transfer oxygen across the three primary areas of the Earth, the Atmosphere, the Biosphere, and the Lithosphere.
Phytoplankton is one of the major oxygen sources, followed by terrestrial plants and trees. Plankton or phytoplankton – is a critical component of oceanic habitats and food chains.

They are the main predators in the seas, feeding on a wide variety of species and other creatures. Many planktons are photosynthetic, which means they contain oxygen. Phytoplankton belongs to the planet of plankton. They play a major role in the oxygen cycle as they photosynthesize. In cold, nutrient-rich waters where they form the basis of the food system, they are common and are an incredibly complex and varied group of species.

Note: Around half of the world's oxygen is provided by phytoplankton via the photosynthesis process, according to National Geographic. These phytoplanktons only require two things to generate oxygen: energy from the sun and nutrients from the water.
