Question

which statement describes an interaction between the biosphere and the atmosphere that is related to photosynthesis?
during photosynthesis, plant roots take in water from soil.
during photosynthesis, plants take in carbon dioxide from the air.
through photosynthesis, energy stored in plants is released into the air.
through photosynthesis, energy stored in plants is transferred to humans who eat them.

Explanation:

Photosynthesis is a process where plants (biosphere) use carbon dioxide (from the atmosphere) and water to produce glucose and oxygen. The interaction between biosphere (plants) and atmosphere (carbon dioxide) is key.

• The first option is about plants and soil (geosphere), not atmosphere.
• The second option correctly shows plants (biosphere) taking in carbon dioxide (from atmosphere) for photosynthesis.
• The third option is incorrect as energy stored in plants is not released into the air during photosynthesis (it's stored as chemical energy in glucose).
• The fourth option is about energy transfer in the food chain (biosphere - biosphere interaction), not with the atmosphere.

Answer:

During photosynthesis, plants take in carbon dioxide from the air.
