What is the main difference between a food chain and a food web?

A food chain shows one path of energy flow, while a food web shows many interconnected food chains.

In a food web, what do the arrows represent?

The arrows represent the direction in which energy is moving from one organism to another.

Primary consumers, secondary consumers, and tertiary consumers.

Producers convert the sun's energy into food, which is the base of the food web.

Secondary and tertiary consumers would have less food, potentially decreasing their populations. Producers might increase due to less consumption.

Food Webs in Ecosystems - Energy Flow and Ecosystem Connections

3 key concepts

1
A food web is a model that shows all the different food chains in an ecosystem.
2
In a food web, the arrows show how energy flows from one organism to another, starting with producers like grass or phytoplankton.
3
Food webs show how interconnected ecosystems are, meaning that if one part of the web changes, it can affect the entire ecosystem.
