Food Chains and Webs

Let's start with reviewing the parts of a food chain. If you need help, click on the animal.

Plants are called producers. Why? Because they produce their own food!

How? They use light energy from the Sun, carbon dioxide from the air and water from the soil to produce food in the form of glucose/sugar. This is called photosynthesis.

HerbivoresHerbivoresEat Plants Only!

Why? Because they cannot make their own food, so they need to consume (eat) plants and/or animals.

There are 3 groups of consumers.

What does each one eat?

Animals are called consumers.

CarnivoresCarnivoresEat Only Animals!

OmnivoresOmnivoresEat Plants & Animals!

Primary Decomposers

Fungi & Bacteria

Fungi and bacteria play an important role in the food chain. They break down dead material and turn them into nutrients in the soil, which plants use to grow.

Creating a food chain.

Remember that a food chain always starts with the sun. The arrows point to the organism gaining the energy. This means they are doing the eating. Scroll down, press play and watch how to create a food chain.

Now let's practice creating a food chain

Remember that a food chain always starts with the sun. The arrows point to the organism gaining the energy. This means they are doing the eating.

Now that you have had some practice, lets try the food chain game. Click on the duck to begin.

A food web is several food chains that overlap. Below write 2 food chains that can be found in this food web.
