Who is the secondary consumer?
the plankton , because it gets eaten by the zooplankton
zooplankton, because it eats the plankton then gets eaten by the small fish.
small fish, because it eats the zoo plankton which ate the plankton.
The shark, which ate he small fish.
Why is the number of trophic levels that can exist limited?
Because there is no predator to eat the Teritary consumers.
A large amount of energy is lost at each level, so there has to be a limit on the number of trophic levels
There wouldn't be anymore producers.
