Levels. The organisms in the trophic levels of the food chain are based
on their pattern.
Quaternary Consumers : consist of
organisms that eat these carnivores.
Tertiary Consumers : feed on secondary
consumers.
Secondary Consumers : are carnivorous
organisms. They feed on herbivorous.
Primary Consumers : are herbivores like fish
and insects. They feed off of the plants and
consume the energy that is transferred.
Producer: consist of organisms that eat
these carnivores.
