Organisms need energy to conduct essential life activities. Basically, energy is essential to every organisms because it is their source of power to get food and to reproduce. Without it, organisms would not function properly and will soon die.
Organic means it is made only of carbon.
Explanation:
The all four types of macromolecule are organic means these all four type of macromolecule made up of carbon. These four macro molecules are carbohydrate, protein, nucleic acid and Proteins. All are essential cell component perform a wide array of function.
Biological macromolecule is organic so they contain carbon. A part of carbon they contain nitrogen, hydrogen and additional minor element. Enzymes and some hormone are example of protein.
