Top Animals Humans Need to Survive - Plankton

Plankton refers to organisms that live suspended in the water which do not have sufficient movement to counteract the currents, although many do move, mainly vertically through the water column. Despite their size, these organisms are important because they serve as food for marine animals such as large blue whales. They can also absorb energy from the sun and nutrients from the water, two ingredients they need for photosynthesis, producing about 50% of the oxygen produced on planet Earth, thus proving to be of vital importance for our continuity on the planet.
