What happens when an animal dies and no one notices?

• Any independent living thing

• Can be as small as a single celled bacteria

• Or as large as a whale!

And the small microbes are very important.

Decomposers

• Decomposers eat dead things and turn them back into dirt, or soil. YUK!

• Examples:–Mushrooms–Worms– Bugs

What would the world look like without decomposers (bacteria and

fungi?)

How they relate
