Answer:
<em>The correct option is A) make food.</em>
Explanation:
Photosynthesis can be described as a process by which organisms like plant and some algae make their own food. They use light energy from the sun to convert carbon dioxide and water into glucose and oxygen. Oxygen is the by- product of this reaction. Hence, option A is correct.
Other options are wrong because photosynthesis is not a process by which energy can be extracted from food or it is not a process by which excretion of waste occurs. Neither is it a process of reproduction.

Answer:

Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. Humans get nitrogen from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an essential component of the nucleic acids DNA and RNA and all of the other molecules derived from the nitrogenous bases.
