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.
What are Consumers? The food chain is composed of producers that make their own food by photosynthesis, such as plants, and consumers, which depend on other organisms for nourishment. Consumers are divided into three categories: Primary consumers are herbivores, animals that eat only plants. Primary consumers include insects, small mammals such as rabbits, and larger mammals such as deer and elk. Secondary consumers are one level up from primary consumers in the food chain. They may be omnivores that eat both plants and animals, or carnivores that eat only animals. The diet of secondary consumers includes primary consumers. Examples of secondary consumers are bears, snakes and foxes. Tertiary consumers are the carnivores at the top of the food chain in a given ecosystem. They eat only meat, and their diet usually includes secondary consumers. Examples of tertiary consumers are hawks and mountain lions.
