Algea and small fish
The barreleye fish is a small fish that lives in the deep to medium-depth parts of the ocean. Because this fish is so small, almost everything eats it, including squid, sharks, and tuna.
In the ocean, a simple food chain could look like this: phytoplankton (producer) is consumed by zooplankton (primary consumer), which is then eaten by small fish (secondary consumer), which are then preyed upon by larger fish (tertiary consumer), and finally, sharks (apex predator) feed on the larger fish.
Puffer fish are eaten by sharks, dolphins, and some larger fish in the ocean.
