Bio accumulation of DDT lead to bird eggs with weak shells and non viable offspring. The lethal effects of DDT on birds was first noted in 1950; scientists discovered that earthworm was accumulating the DDT pesticide and that the robins that were preying on the earthworms were been poisoned. Further research revealed that the chemical cause thinning of the egg shell and production of non viable offspring. The chemical has since been banned in USA.

Answer:
<h2>5.storage of energy</h2>
Explanation:
- Proteins are important biomolecules that are a type of macromolecule.
- This macromolecule is made up of a monomer that is called amino acid.
- There are many functions of the protein molecules in living organisms.
- They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
- Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
- Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
- They also play an important role in the immune system.
- The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
