Unit 2: Food Webs

A food web is a complex network of interconnected food chains that shows how energy and nutrients flow through an ecosystem.

An organism that makes its own energy, typically through photosynthesis, such as plants.

An organism that eats other organisms for energy, including herbivores, carnivores, and omnivores.

An organism that breaks down dead organisms and organic waste, returning nutrients to the soil, such as fungi and bacteria.

An organism that eats both plants and animals for energy.

Producers are the foundation of a food web, providing energy for consumers.

An organism that only eats plants for energy.

An organism that only eats other animals for energy.

Energy flows from producers to consumers and then to decomposers.

Decomposers recycle nutrients back into the soil, making them available for producers.
