Question

All living things need energy to survive. The most common source of energy for organisms is glucose molecules, which are used as food. A plant’s food is no exception. Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis? A. from the ground B. from the air C. from the water D. from the sun

Answer 1

The correct answer is B. from the air.

Step-by-step explanation:

Plants get the carbon needed to make glucose molecules during the process of photosynthesis from the air.

During photosynthesis, plants use the energy of sunlight, carbon dioxide gas (CO₂), and water to create glucose (C6H12O6) and oxygen. This process involves synthesizing a larger, energy-storing molecule and requires an input of energy to proceed. The equation for the synthesis of glucose is: 6CO2 + 6H₂O + energy → C6H₁2O6 + 602.

Therefore, the correct answer is B. from the air.
