Question

select all the correct answers. which natural methods remove co2 from the atmosphere? respiration of living organisms, photosynthesis by plants, evaporation of ocean water, absorption of co2 from the atmosphere by ocean water, melting of glacial ice

Explanation:

• Respiration of living organisms: Organisms release \( CO_2 \) during respiration, so it does not remove \( CO_2 \) from the atmosphere.
• Photosynthesis by plants: Plants take in \( CO_2 \) and use it to make glucose, thus removing \( CO_2 \) from the atmosphere.
• Evaporation of ocean water: This process involves water changing state and does not remove \( CO_2 \).
• Absorption of \( CO_2 \) from the atmosphere by ocean water: Ocean water can absorb \( CO_2 \) from the air, removing it from the atmosphere.
• Melting of glacial ice: This is a phase change of ice and does not involve \( CO_2 \) removal.

Answer:

• Photosynthesis by plants
• Absorption of \( CO_2 \) from the atmosphere by ocean water
