Diatoms

Vedclass · Answer

(D) In an aquatic ecosystem,the primary producers are often microscopic organisms like phytoplankton. Among these,diatoms are highly significant. Diatoms are unicellular algae that possess a unique cell wall made of silica (frustule). They are extremely abundant in oceans and freshwater bodies and serve as the main source of food for many aquatic organisms. Due to their rapid rate of reproduction and massive population density,they contribute significantly to the total biomass of the aquatic ecosystem.

Which of the following is responsible for the high biomass in an aquatic ecosystem?
