Aqualing — Ocean Depth & Adaptations Sharkglass Trench

Hi!

I'm Aqualing.

Welcome to Sharkglass Trench!

Will you help me investigate ocean depth & adaptations?

The Grumblies have mixed up our clues.

Let's check the evidence!

Sunlight decreases with ocean depth.

Deep water is generally cold,

and pressure increases as more water lies above.

What usually decreases with depth?

  • A. Sunlight
  • B. Pressure
  • C. Water above the organism

The answer is A: Sunlight

Sunlight decreases with ocean depth.

Deep water is generally cold,

and pressure increases as more water lies above.

That clue helps us make sense of this place.

Ocean organisms have varied structures and behaviors suited to their conditions.

Some deep-sea animals produce light;

many rely on food originating elsewhere.

What increases as more water lies above?

  • A. Available sunlight
  • B. The amount of sunlight
  • C. Pressure

The answer is C: Pressure

Sunlight decreases with ocean depth.

Deep water is generally cold,

and pressure increases as more water lies above.

Hmm...

how does that connect to our first clue?

Our remote records compare a bright shallow site

and a dark deep site.

A light-sensitive structure or light-producing signal could be useful in darkness;

a plant requiring sunlight would lack that energy source there.

Which site lacks sunlight for a sun-dependent plant?

  • A. Both sites have identical light
  • B. The dark deep site
  • C. The bright shallow site

The answer is B: The dark deep site

Our remote records compare a bright shallow site

and a dark deep site.

A light-sensitive structure or light-producing signal could be useful in darkness;

a plant requiring sunlight would lack that energy source there.

Nice investigating!
