[amp_mcq option1=”O2″ option2=”CO” option3=”N2″ option4=”CO2″ correct=”option4″]<\/p>\n

The correct answer is D. CO2.<\/p>\n

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. The chemical equation for photosynthesis is:<\/p>\n

6CO2 + 6H2O + light energy \u00e2\u0086\u0092 C6H12O6 + 6O2<\/p>\n

As you can see from the equation, carbon dioxide is a reactant in photosynthesis. It is used by plants to create glucose, a type of sugar. Glucose is then used by plants for energy or to build new plant material.<\/p>\n

Oxygen is a product of photosynthesis. It is released into the atmosphere as a waste product.<\/p>\n

Water is also a reactant in photosynthesis. It is used by plants to split apart the carbon dioxide molecules.<\/p>\n

Light energy is also required for photosynthesis. It is used by plants to split apart the water molecules.<\/p>\n

The other options are not necessary for photosynthesis.<\/p>\n
