What is a Food Web?

Why is it called a food web? What does it have to do with energy?

Producers

Producers are the base of the food web, capturing energy and storing it in a form that living things can use.

Primary Consumers

Primary consumers are usually herbivores, eating plants to get their stored energy.

Secondary Consumers

Secondary consumers are predators, animals that eat other animals.

Scavengers and Decomposers

Meet the "clean up crew" of the food web.

Providing information about the calorie

Providing information about the calorie: The calorie is a unit of energy that is used to express the energetic power of food, and thus, all foods provide calories.
