A Correct answer
Explanation

Diatoms are unicellular algae that belong to the group of photosynthetic phytoplankton. They are characterized by their unique silica-based cell walls called frustules, which are often intricately patterned. Diatoms are not protozoans, bryophytes, or detritivores - they are primary producers in aquatic ecosystems.
