The top five primary consumers in the ocean include zooplankton, which feed on phytoplankton; small fish such as anchovies and sardines that consume various plankton; sea urchins that graze on algae; herbivorous marine mammals like manatees; and some species of marine turtles that feed on seagrasses and algae. These organisms play a crucial role in the marine food web, converting primary production into energy for higher trophic levels.
There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.
Most insects, some lizards, some birds, tortoises, large herbivores - any animal that feeds on plants or seeds are primary consumers.

In an ocean ecosystem, five first-level consumers include zooplankton, small fish like anchovies, krill, sea urchins, and certain types of mollusks such as clams. These organisms primarily feed on primary producers like phytoplankton and marine algae, converting the energy from these producers into forms that higher trophic levels can utilize. They play a crucial role in the marine food web by transferring energy from autotrophs to higher-level consumers.
If you mean that can tertiary and quaternary consumers both be carnivores, then yes, they can be. The quaternary consumers are probably at the top of the food chain as there are rarely any more than 4 - 5 trophic levels. This is because it would be pointless as there would be very little energy left for the top consumer.If you actually mean what you said literally in the question then the top consumer can eat carnivores but it is highly unlikely that the tertiary consumer will eat carnivores - they usually eat omnivores (secondary consumers) who eat herbivores (primary consumers) who eat producers (e.g. plants).
A meat-eater that eats primary consumers is a secondary consumer. Then goes the tertiary consumer, quartenary consumer, etc. It only goes up to 5 though, because the energy from the sun is so low after the 5th one.

Wolves, coyotes, foxes and other wild canines. Cougar, bobcats and other feline species. Any animal that feeds on primary consumers is a secondary consumer.
