Read the following statements carefully: A. Diatoms are the chief producers in the oceans. B. Dinoflagellates are mostly fresh water and heterotrophic. C. Euglenoids are photosynthetic in the presence of sunlight and behave like heterotrophs when deprived of sunlight. D. Slime moulds are parasitic protists. E. All protozoans are heterotrophs and live as predators or parasites. How many of the above statements are cor

Step-by-step solution

Statement A is correct as diatoms are the chief producers in the oceans. Statement B is incorrect because dinoflagellates are mostly marine and photosynthetic.
