Food Webs and Ecosystems

A single food chain is one line of who-eats-whom — but real habitats weave many chains into a food web, and every strand traces back to the Sun.

A Tangled Meadow

Kavi glides over a meadow 🌾 and grins. "Last time we followed ONE line: grass → grasshopper → frog. But look closer! The rabbit ALSO eats the grass 🐰, a fox hunts the rabbit 🦊, and I could swoop for the frog OR the fox! 🦅 So many lines cross over." "When food chains tangle together like this, we call it a food web. And every single strand — follow it back far enough — begins at the Sun. ☀️ Let's untangle it!"

What your child will learn

1From a food chain to a food webA whole habitat is more than one chain. Tap each idea to learn what it means.

2Follow a hawk's energy back to the SunStart at the top predator and tap your way down. Each arrow asks: where did THAT energy come from?

3Producer, consumer or decomposer?Every living thing in an ecosystem has a job. Sort each one by the role it plays.

4What happens in the web?A food web is a connected system. Predict what happens, then tap to check. Tap Next test for more.

A peek inside

Kavi finds a web with two chains: grass → grasshopper → frog, and grass → rabbit → fox. Both chains share one living thing. Which is it?

Look at what starts each chain. The grasshopper's chain begins with grass, and the rabbit's chain also begins with grass. The grass is the producer shared by both — and that sharing is exactly what links two chains into a web.

Try this at home: What do we call many food chains that overlap in one habitat?
