carbon dioxide
True
They combine to make sugars & starches and give off oxygen as a waste product
Carbon and oxygen combine easier!
If they are chemically combined, a compound eg a molecule of carbon dioxide contains an atom of carbon and two atoms of oxygen. Carbon dioxide is a compound.
When elements combine chemically compounds are formed. For instance, when hydrogen and oxygen gases chemically combine, water is formed. Note that if a molecule is made up of only one element, it is referred to as an element, not a compound.
Carbon dioxide is the product of a combustion reaction.
CO
In photosynthesis, carbon dioxide and water combine to form glucose and oxygen. Oxygen is the gaseous product in photosynthesis.

None. If carbon, hydrogen, and oxygen happen to chemically combine, they form an organic compound. 'Compound', not element. (These 3 substances are each an element).
The three elements that make up glucose are carbon, hydrogen and oxygen. These can be in the form of carbohydrates or sugars.
This is the law om mass conservation.
