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.
All protozoans are consumers, and many have interestingways of taking in food.Some,like Paramecium ,use cilia to sweepfood into mouthlike openings. Others, like amoebas, surroundand trap food particles, such as a bacterium, with pseudopods.The food is then enclosed in a sphere called a vesicle.
