Solution:

There are certain biomolecules which do not play a direct role in the growth and development of the organisms but are produced by them. Such biomolecules are called as secondary metabolites. These include alkaloids, flavonoids, rubber, essential oils, antibiotics, coloured pigments, scents, gums, and spices among many other. Hence, all the given examples are part of secondary metabolites.
