Question

what sphere is the carbon atom moving between?
word bank - geosphere, hydrosphere, biosphere, atmosphere

what process causes the carbon to move?
word bank - photosynthesis, cellular respiration, decomposition, combustion

what molecule is the carbon atom moving between?
word bank - carbon dioxide, fat, fuels, glucose

Explanation:

• First question: The biosphere is the sphere where life exists. Carbon moves from the atmosphere (where it is in the form of \(CO_2\)) to the biosphere (in plants as glucose) through photosynthesis.
• Second question: Photosynthesis is the process by which plants take in \(CO_2\) from the atmosphere and convert it into glucose (\(C_6H_{12}O_6\)) using sunlight. The chemical equation for photosynthesis is \(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\).

• Third question: As mentioned above, during photosynthesis, carbon moves from carbon - dioxide (\(CO_2\)) in the atmosphere to glucose (\(C_6H_{12}O_6\)) in the biosphere.

Answer:

• First blank: biosphere
• Second blank: photosynthesis
• Third blank: glucose
