Wriggling — Microbes as Decomposers Decomposer Dump

Hi!

I'm Wriggling.

Welcome to Decomposer Dump!

Will you help me investigate microbes as decomposers?

The Grumblies have mixed up our clues.

Let's check the evidence!

Many microbes act as decomposers, breaking down dead material and wastes.

This contributes to returning matter to the environment.

What do decomposers break down?

  • A. Dead material and wastes
  • B. Only sunlight
  • C. Only living sunlight

The answer is A: Dead material and wastes

Many microbes act as decomposers, breaking down dead material and wastes.

This contributes to returning matter to the environment.

That clue helps us make sense of this place.

Materials can later support other organisms, including plants.

Energy does not cycle back in exactly the same way as matter.

Where can returned materials go?

  • A. Out of existence forever
  • B. Only into empty space
  • C. Into soil and other environmental stores

The answer is C: Into soil and other environmental stores

Materials can later support other organisms, including plants.

Energy does not cycle back in exactly the same way as matter.

Hmm...

how does that connect to our first clue?

Our diagram traces fallen leaves through decomposer activity to materials in soil.

Microbes are part of ecosystem connections, not simply unwanted dirt.

Can plants later use some returned materials?

  • A. Only if they become animals
  • B. Yes
  • C. No

The answer is B: Yes

Materials can later support other organisms, including plants.

Energy does not cycle back in exactly the same way as matter.
