  1. Photosynthesis

  2. Respiration

  3. Transpiration

  4. Decomposition
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen, absorbing carbon dioxide from the atmosphere.

Multiple choice

What is the term for the process by which pollutants are removed from water by natural processes?

  1. Biodegradation

  2. Photodegradation

  3. Volatilization

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biodegradation, photodegradation, and volatilization are all processes by which pollutants are removed from water by natural processes. Biodegradation is the process by which microorganisms break down pollutants into harmless substances. Photodegradation is the process by which pollutants are broken down by sunlight. Volatilization is the process by which pollutants evaporate from water into the air.
