Answer:
The correct options are B and D
Explanation:
Carbon dioxide (CO₂) is primarily produced during respiration by animals. This carbon dioxide is absorbed from the atmosphere in two ways
- by plants through photosynthesis
- by ocean water
Plants breath in CO₂ and breath out oxygen (O₂) during photosynthesis. Photosynthesis is the process by which green plants produce there own food on there own. Consider the following reaction
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
From the reaction above, the CO₂ (with water) is taken in during photosynthesis to produce glucose (C₆H₁₂O₆). The usage of CO₂ by plants assist in removing it from the atmosphere.
CO₂ can dissolve in water to form carbonic acid (H₂CO₃). Based on this principle, ocean water also dissolves CO₂ from the air when air comes in contact with the ocean water.
