Answer:
- - Phytoplanktons are the marine creations of the autotrophic plants found on the surface of the Earth.
- - Just like the plants on the surface of the Earth, phytoplanktons also take in carbon dioxide & give out oxygen by absorbing sublight & conducting the process of photosynthesis.
- They also form the base of the marine food-chain just like the terrestrial autotrophic plants.
- - Phytoplanktons are found to be largely located in the surface of oceans near to the coastlines, higher altitudes, or near to the equator.
- - This is because phytoplanktons need a lot of nutrients to survive & hence live near to the surface of oceans to get enough sunlight which helps in photosynthesis.
