Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is needed to produce carbohydrates and other compounds from carbon dioxide
A
light
B
water
C
energy
D
smoke
Explanation: 

Detailed explanation-1: -Energy is needed to produce carbohydrates and other carbon compounds from carbon dioxide. Temperature, light intensity and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis.

Detailed explanation-2: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-3: -Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air.

Detailed explanation-4: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

Detailed explanation-5: -Answer and Explanation: Plants are autotrophs, which means they make their own food. They do this through the photosynthesis reaction, which takes carbons dioxide, water, and energy from sunlight to produce carbohydrates (i.e. the food) and oxygen.
