Trophic levels describe the specific feeding positions that organisms occupy within a food chain. A healthy ecosystem typically features four major levels:

• Level 1 (Producers): Plants and algae that make their own food.

• Level 2 (Primary Consumers): Herbivores that eat the plants.

• Level 3 (Secondary Consumers): Carnivores that eat the herbivores.

• Level 4 (Tertiary Consumers): Top carnivores that eat other carnivores.
