BIOCENOSIS

MARINE ORGANISMS BENTHONIC ORGANISMS: LIVE IN OR ON THE SEABED, THEY CAN BE FIXED OR MOVE AROUND BENTHONIC ORGANISMS: LIVE IN OR ON THE SEABED, THEY CAN BE FIXED OR MOVE AROUND PELAGIC ORGANISMS PELAGIC ORGANISMS NEKTONIC: SWIM ALL TIME DONT DEPEN ON WATER CURRENTS TO MOVE AROUND PLAKTONIC: FLOAT IN WATER CURRENTS, MAINLY MADE UP OF MICROSCOPIC ORGANISMS, CAN ALSO CONTAIN INVERTEBRATES

TROPHIC PYRAMIDS DEEP-SEA ORGANISMS FEED ON PLAKTON, THIS IS PARTIALLY COMPOSED OF MICROSCOPIC PHOTOSYNTHETIC ALGAE, WHICH ARE EATEN BY LARGER MARINE ORGANISMS. THIS MARINE ORGANISMS ARE THEN EATEN BY LARGER ANIMALS DEEP-SEA ORGANISMS FEED ON PLAKTON, THIS IS PARTIALLY COMPOSED OF MICROSCOPIC PHOTOSYNTHETIC ALGAE, WHICH ARE EATEN BY LARGER MARINE ORGANISMS.
