A Food web is a network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem. Sometimes scientists describe each level in a food web with a trophic level. Here are the five trophic levels:
- Level 1: Plants (producers)
- Level 2: Animals that eat plants or herbivores (primary consumers)
- Level 3: Animals that eat herbivores (secondary consumers, carnivores)
- Level 4: Animals that eat carnivores (tertiary consumers, carnivores)
- Level 5: Animals at the top of the food chain are called apex predators. Nothing eats these animals.
