Which is the reason for highest biomass in aquatic ecosystem :Biomass is the total mass of living matter present at a time.
In coastal aquatic ecosystems, large benthic (bottom-dwelling) algae such as brown algae (kelps, which can grow to tens of metres) form dense beds and contain a very large standing biomass.
Phytoplankton (nanoplankton, diatoms) are very productive but have a small standing biomass at any time, because they are rapidly eaten.
So, as per the answer key, the highest biomass in an aquatic ecosystem is due to benthonic and brown algae.
