Cellular organelles are the internal organs of a cell. They are responsible for keeping the cell alive. They do this by bringing in food for the cell, getting rid of waste, protecting and repairing the cell, and helping it grow/reproduce.

The algae in the ocean have a very high Net Primary Productivity (NPP) and a very low amount of store biomass. This is because THE GROWTH RATE OF ALGAE IN THE OCEAN IS HIGH. The store biomass is low because THE PRIMARY CONSUMERS FEED ON THESE ALGAE THUS LOWERING THE BIOMASS AMOUNT. The production of biomass is related to the NPP.
