Question

which statement describes an interaction between the biosphere and the hydrosphere?
plant roots take in water through their roots.
plants take in carbon dioxide from the air.
energy stored in plants is transferred to humans and animals that eat them.
plants make food through photosynthesis and release oxygen into the atmosphere.

Explanation:

• The biosphere includes living organisms (like plants), and the hydrosphere includes water bodies and water in general.
• For the option "Plant roots take in water through their roots": Plants (biosphere) interacting with water (hydrosphere) as they absorb water from the hydrosphere.
• "Plants take in carbon dioxide from the air": This is biosphere - atmosphere interaction (atmosphere is not hydrosphere).
• "Energy stored in plants is transferred to humans and animals that eat them": This is interaction within the biosphere (between different living organisms).
• "Plants make food through photosynthesis and release oxygen into the atmosphere": This is biosphere - atmosphere interaction.

Answer:

A. Plant roots take in water through their roots.
