Aqualing — Marine Food Webs & Relationships Coral Crown Reef

Hi!

I'm Aqualing.

Welcome to Coral Crown Reef!

Will you help me investigate marine food webs & relationships?

The Grumblies have mixed up our clues.

Let's check the evidence!

Many ocean food webs begin with producers

such as phytoplankton or algae using sunlight.

Consumers get food by eating organisms.

Where should an arrow point from a grazer eaten by a fish?

  • A. Away from both organisms
  • B. Toward the fish
  • C. Toward the grazer from the fish

The answer is B: Toward the fish

Food-web arrows show energy moving from food to eater.

In our model, phytoplankton feed small grazers and the grazers feed fish.

That clue helps us make sense of this place.

Food-web arrows show energy moving from food to eater.

In our model, phytoplankton feed small grazers and the grazers feed fish.

Which is a producer in this model?

  • A. Phytoplankton
  • B. The fish
  • C. The grazer

The answer is A: Phytoplankton

Many ocean food webs begin with producers

such as phytoplankton or algae using sunlight.

Consumers get food by eating organisms.

Hmm...

how does that connect to our first clue?

If producers decline, less food may be available to grazers

and then fish.

Real webs have many links,

so the size of each effect needs evidence.

What might producer decline cause?

  • A. Guaranteed unlimited food for fish
  • B. Producers become unnecessary
  • C. Less food for grazers

The answer is C: Less food for grazers

If producers decline, less food may be available to grazers

and then fish.

Real webs have many links,

so the size of each effect needs evidence.
