Which of the following DECREASE as you go deeper in the ocean? Check all that apply.

1)Temperature
2)Phytoplankton
3)Sunlight
4)Pressure

1 answer

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.
