C) heterotrophs
D) autotrophs
Correct Answer: D
Solution :
Phytoplanktons are photosynthesizing plankton consisting chiefly of microscopic algae, such as diatoms and dinoflagellates. They are of great importance as they form the basis of food for all other forms of aquatic life, being the primary producers.
