Protein being the macro molecule is involved in almost every function of the body. Some of the important functions of the protein in the body are given below.
- Like our nails and hair are made of keratin protein.
- All the enzymes that is involved in the metabolic reactions of the body are protein.

Answer:
The amount of energy
Explanation:
<em>The percentage represents the amount of energy at each trophic level of the food chain/web.</em>
<u>A trophic level represents a hierarchical level in a food chain or food web in an ecosystem with each level consisting of organisms that share the same function and nutritional relationship to energy source.</u>
The amount of energy in each trophic level decreases as we move up the food chain/web due to a loss to the environment as heat.
In the image, the first level represents the primary producer that are responsible for fixing energy directly from the sun. Hence, they posses 100% of the energy in the food web.
The second level represents the first-level consumers of primary producers. The amount of energy that gets to these consumers has reduced from 100% to 10%, meaning that 90% has been lost as heat to the environment.
The third level represents the second-level consumers. That is, those that directly feed on the first-level consumers. The amount of energy they derive has also reduced from 10% to 1% while in the third-level consumers, the amount of energy derived has reduced to 0.1%.
