Which best describes the MOST LIKELY effect on the Phytoplankton’s biomass if more Plankton moved into the ocean ecosystem?
The biomass would be higher because there would be fewer phytoplankton to store energy.
Biomass would be higher because there would be less energy lost as heat from the phytoplankton.
The Biomass would be lower for the phytoplankton since there are more consumers now.
Biomass would be lower because there would be more energy lost as heat from the phytoplankton.
