Summary Introduction
Introduction :
Different techniques are employed by organisms to get the energy needed for growth, reproduction, and survival. Using light or chemical energy, certain organisms can convert atmospheric carbon into molecules that are high in energy. For their energy needs, some creatures rely on other organisms. Organisms can be divided into many categories according to the source of their energy.
