Seawater is the natural habitat of a rich biological variety of microorganisms that are called marine plankton. Plankton is found in the high and intermediate areas of the sea and is the main and most abundant nutrient in the food chain for aquatic animals, from the microscopic ones to the largest ones like whales.
Plankton is divided into two types: phytoplankton that is vegetal plankton, the micro seaweed and the zooplankton that is made of animals, larva and eggs. In order to see these microorganisms, it is necessary to use a microscope in most cases.
This great variety of live material is what brings proteins, vitamins, carbohydrates and fatty acids into the seawater. This is the reason why, as well as the minerals that seawater contains, it is a complete organic nutrient that nature provides. Its daily consumption, in adequate doses, contributes to bringing balance in nutrients for humans and animals.
Thanks to photosynthesis, phytoplankton plays an extremely important role as it brings oxygen to the atmosphere and contributes to almost 50% of the oxygen we breathe.
