Question

the earths four main spheres continuously interact to support life and balance earths materials. when plants absorb carbon dioxide for photosynthesis, it is an example of____ and____ sphere interaction.
○ hydrosphere, lithosphere
○ biosphere, atmosphere
○ biosphere, lithosphere
○ cryosphere, lithosphere

Explanation:

To solve this, we analyze the spheres involved:

• The biosphere includes living organisms (plants).
• The atmosphere contains carbon dioxide.
• When plants (biosphere) absorb CO₂ from the atmosphere for photosynthesis, it's an interaction between the biosphere and atmosphere.
• The hydrosphere relates to water, lithosphere to rocks/soil, cryosphere to ice—these don't fit here. So the correct interaction is biosphere and atmosphere.

Answer:

B. biosphere, atmosphere
