Question

Which of the following DECREASE as you go deeper in the ocean? Check all that apply.
1)Temperature
2)Phytoplankton
3)Sunlight
4)Pressure

Answer 1

As you go deeper in the ocean, the following typically DECREASE:

1) **Temperature** - Temperature generally decreases with depth in the ocean.
2) **Phytoplankton** - Phytoplankton, which rely on sunlight for photosynthesis, tend to decrease in abundance as you go deeper where there is less light.
3) **Sunlight** - Sunlight decreases with depth in the ocean due to absorption and scattering by water.

**Pressure**, on the other hand, increases with depth in the ocean.

So, the correct answers are: **Temperature, Phytoplankton, and Sunlight.**
