What are phytoplankton? How are they important to our ecosystem?

Solution

Phytoplanktons are the grasses of the sea of the Southern Ocean. These are single celled plants and use the sun’s energy. With the process of photosynthesis, they supply food and oxygen for all the marine life of the sea. But the global warming can affect the activities of these plants and life of all the creatures depending on them. Global warming also causes the melting of the ice-bergs and collapsing of ice-shelves in the region.

The phytoplanktons convert carbon dioxide and water into food using energy from sunlight. If they fail to do so the temperature of the earth would rise. The ozone layer will get depleted and the ultra-rays would reach the earth. The earth would become unduly warm. Therefore, it is very important for our eco-system.
