Which organism floats?

Which organism is swimming?

Which organism is non-moving?

The ocean is made up of water, dissolved gases, dissolved salt, and other particles. Why is it important that it contains dissolved gases?

• Marine organisms depend on it for survival.

• It helps matter to decay faster.

• It allows sediments to dissolve into the water.

This midwater jelly can light up its long tentacles to distract a potential predator long enough to escape. If that doesn't work, it can detach its tentacles and flee.

What inference can you make about where this marine organism lives?

• It must live on the continental shelf to absorb light from the sun.

• It must live on the continental slope because it needs the sun

• It must live in the oceanic trench because it is the deepest and darkest area.

• It must live on the abyssal floor because it is the deepest and darkest area.
