Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Identify the main energy source that is a reactant in photosynthesis
A
Glucose
B
Sunlight
C
Water
D
Carbon Dioxide
Explanation: 

Detailed explanation-1: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-2: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.

Detailed explanation-3: -The reactants of photosynthesis are everything to the left of the “—>” arrow, thus the reactants of photosynthesis are carbon dioxide, water, and sunlight energy.

Detailed explanation-4: -The sun is the source of almost all energy on Earth. It enables plants and other organisms to turn water and carbon dioxide into sugars through a process called photosynthesis. The sun releases light that travels many millions of miles through space. A unit of that light is known as a photon.

Detailed explanation-5: -During photosynthesis, light energy (sunlight) combines with the reactants-water and carbon dioxide-to form new products: glucose (sugar) and oxygen.
