Add butter/olive oil combination. Add the fillets, without crowding. Increase heat to high and saute, shaking the pan from time to time, until the bottom of the fish is nicely browned, about 3 minutes. Turn and brown the other side. Remove fish to a plate and keep warm in the oven. Repeat with remaining fillets.
Copepods are considered to be primary consumers. They form an important link in the food chain. Their diet consists of small plant plankton.
Consumers have to feed on producers or other consumers to survive. Deer are herbivores, which means that they only eat plants (Producers). Bears are another example of consumers. Black bears are omnivores and scavengers, like skunks and raccoons, which means that they will eat just about anything.
