Plankton normally thrive in bodies of water including lakes, oceans, seas and rivers. They live in the euphotic zone, which is the section in bodies of water that can be penetrated by sunlight. These plants produce a large percentage of the oxygen available in the world today since they also develop by photosynthesis.
Planktons are microscopic plants that generally live in the ocean´s surface. They use chlorophyll to turn sunlight in order to grow and develop. These plants are unique because they do not have features of other plants like roots, stems or leaves. They form the base of the food chain meaning that many organisms at the low end of the chain feed on them.
Planktons are essential to Earth´s environment because they take in carbon dioxide during photosynthesis and release oxygen as a by product. They also absorb high quantities of carbon dioxide making it possible for Earth to remain free of climatic effects such as global warming which is facilitated by high amounts of carbon in the air. Oceans contain huge amounts of carbon which are stored in planktons, effectively acting as a filter and protecting other marine life from harmful effects of carbon.
