Question #2ec51

Answer 1

Oxygen gas `O_2`

Explanation:

Photosynthesis (click this for a video) is the process by which plants produce their "food." While humans, dogs, cats, and other animals consume plants and other animals for energy, plants use energy from the sun to make glucose, a type of sugar.

The "Recipe" for Photosynthesis
If you have ever baked or cooked something, you know that it requires a recipe. Similarly, plants follow a chemical formula that is essentially the "recipe" for glucose. Here it is:

The plant takes in carbon dioxide (`CO_2`) and water (`H_2O`), and using the sun's energy, turns these ingredients into glucose (`C_6H_12O_6`) and oxygen (`O_2`). Since plants don't intend to produce oxygen, and glucose is the primary product of the reaction, oxygen gas ( `O_2`) is the byproduct of photosynthesis.
