Biological energy refers to the energy stored in the bonds of organic molecules, primarily carbohydrates, fats, and proteins, which are the building blocks of living organisms. This energy is harnessed through various biological processes, such as photosynthesis, respiration, and fermentation, to sustain life and drive biological activities.

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, or sugar. This process occurs in the chloroplasts of plant cells and is essential for the production of oxygen and the growth of plants.

Respiration is the process by which organisms break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate), which is used to power cellular activities. This process occurs in the mitochondria of eukaryotic cells and is essential for the survival of all living organisms.

Fermentation is a process by which organisms convert carbohydrates into alcohol or lactic acid without the use of oxygen. This process is used by some bacteria and yeast to produce food and beverages, such as beer and wine.

Biological energy is a renewable resource, as it is constantly being produced by living organisms. However, the use of biological energy is often limited by factors such as the availability of sunlight, the efficiency of energy conversion, and the environmental impact of energy production and use.
