Secondary metabolism (also called specialized metabolism) is a term for the pathways and small molecule products of metabolism that are involved in ecological interactions but are not necessary for organism survival. These molecules are sometimes produced by specialized cells, such as laticifers in plants. Secondary metabolites commonly mediate antagonistic interactions, such as competition and predation, as well as mutualistic ones, such as pollination and resource mutualisms. Examples of secondary metabolites include antibiotics, pigments, and scents. The opposite of secondary metabolites are primary metabolites, which are considered essential for the normal growth or development of an organism.

Secondary metabolites are produced by many microbes, plants, fungi and animals that usually live in crowded habitats, where chemical defense represents a better option than physical escape. It is challenging to distinguish between primary and secondary metabolites due to the overlapping of the intermediates and pathways of primary and secondary metabolism. Sterols serve as an example as they are a product of secondary metabolism as well as represent a base for a cell structure.

Citation Practice
I am practicing my citations and references. I am not using actual references, but instead am using "random" websites to practice the process of citation. I'm going to add one citation for good measure. I'm just kidding, I'm going to do one more citation so I can practice using Wikicode.
