The polymerization of amino acids produces

Polymerization of amino acids leads to formation of proteins. Amino acids are small molecules, composed of an amino group, a carboxyl group, a hydrogen atom, and an ‘R’ group.  

During polymerization, two amino acids bind with each other with the help of peptide bond, which is formed between the amino group of one amino acid and carboxyl group of another amino acid.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
