There are relatively few different types of macromolecular monomers. what is an advantage of constructing protein and carbohydrate macromolecules and the nucleic acids as polymers?

The main advantage of monomers or basic subunits of macromolecules is their simplicity. The simple monomeric subunits from which all proteinsnucleic acids, fats and carbohydratesare constructed are few in number and identical in all living species.These simple monomerc units can be linked in many different combinations (different covalent bonds) to produce complex biological polymers with different functions.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
