Sagot :
*The Producers - the phytoplankton on the ocean's surface. *The Primary Consumers – the coral, sea turtle, and fish. *The Secondary Consumers – the sharks, anemones, starfish, baracuda, jellyfish, sea snakes and sea slugs. The Scavengers – the fish.
First of all, the arrows indicate what is being eaten by what. The organism at the head of the arrow eats the organism at the other end of the arrow.
This particular food web starts with Phytoplankton, a photosynthetic primary producer that receives its energy from the sun and does not need to consume any organism.
The Phytoplankton is consumed by Zooplankton, a primary consumer.
The Zooplankton is then consumed by some secondary consumers: the Fan Worm, the Blue Chromis, the Sea Sponge the Coral Polyps.
The Fan Worm is eaten by the tertiary consumer, the puffer fish.
The Coral Polyps are eaten by a tertiary consumer, the Sea Slug.
The Sea Sponge is eaten by the angelfish.
Finally, the Angelfish, the Blue Chromis and the Butterfly Fish are all consumed by the tertiary consumer, the reef shark.
