Linkling — Water, Air, Soil & Living Things Stream Exchange Crossing

Hi!

I'm Linkling.

Welcome to Stream Exchange Crossing!

Will you help me investigate water, air, soil & living things?

The Grumblies have mixed up our clues.

Let's check the evidence!

Water, air and soil connect with living things.

Plants take up water and minerals

and use carbon dioxide from air to make food.

What do plant roots take up?

  • A. Only solid stones
  • B. Water and dissolved minerals
  • C. Only ready-made sugars from soil

The answer is B: Water and dissolved minerals

Water, air and soil connect with living things.

Plants take up water and minerals

and use carbon dioxide from air to make food.

That clue helps us make sense of this place.

Animals depend on water and food, often linking them indirectly to plants

and soil conditions.

A change in a nonliving resource can affect living populations.

Can soil moisture affect consumers indirectly?

  • A. Yes, through plants
  • B. No, animals are separate from plant conditions
  • C. Only if soil becomes an animal

The answer is A: Yes, through plants

Animals depend on water and food, often linking them indirectly to plants

and soil conditions.

A change in a nonliving resource can affect living populations.

Hmm...

how does that connect to our first clue?

Our dry-soil record shows reduced plant growth followed by less

food for a grazer.

Trace the connection through resources rather than treating each change as unrelated.

What happened first in our record?

  • A. Grazer food became unlimited
  • B. Plants gained unlimited food
  • C. Soil became drier

The answer is C: Soil became drier

Our dry-soil record shows reduced plant growth followed by less

food for a grazer.

Trace the connection through resources rather than treating each change as unrelated.

Nice investigating!
