Answer 1

a. respiration of living organisms

D. absorption of CO2 from the atmosphere by ocean water

Answer 2

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.
