In Biology, energy refers to the capacity of living organisms to perform work, which is essential for growth, metabolism, reproduction, and maintenance of homeostasis. It is primarily derived from the conversion of nutrients through processes like cellular respiration and photosynthesis. Organisms utilize this energy in various forms, such as ATP (adenosine triphosphate), to fuel biochemical reactions and physiological functions. Overall, energy is vital for sustaining life and enabling biological processes.

Understanding energy is important to the study of biology because energy is required for all cellular processes, such as growth, reproduction, and metabolism. Cells need energy to perform these functions efficiently. Moreover, understanding energy flow in biological systems helps explain processes like photosynthesis and cellular respiration, which are central to how organisms obtain and utilize energy.

In biology, the calorie is a unit of heat energy. The calorie is used to measure the amount of energy in the chemical bonds in molecules. A calorie is the amount of energy it takes to increase the temperature of 1 gram of water 1°C. Our normal use of the term 'calorie' is used to describe the amount of heat energy in food, but we actually use the kilo-calorie. For example, a cheeseburger that is advertised as having 300 calories actually contains 300,000 calories of energy.
Biology is called life science because it is the study of all living organisms. It does not focus on anything that is not alive.
It is an energy carrying molecule.It is the universal currency of energy in biology

Humans (and other animals) derive their energy from digesting food which is eaten. The mechanism is a subject for biology, so I should rephrase your question as 'How do humans get their energy from food?' and put it into the Biology section.
they produce the source of chemical energy for themselves and for other organisms. -Biology
Substances in Biology that provide energy as the result of a chemical change are called?
Temperature.
We turn Energy into Heat
Aerobic biology processes require oxygen to produce energy, while anaerobic biology processes do not require oxygen. Aerobic processes are more efficient and produce more energy, while anaerobic processes produce energy more quickly but less efficiently.
Bioenergetics
In biology ATP is energy rich , it is made up of adenosine , ribose and phosphates .
it is a diagram in which arrows show the passing of energy (on animal eating another) in a pond. I is doing this in Biology!
The most common unit of energy in Biology is calories. A calorie is a unit of energy, require to raise 1 kilogram of water to 4.1868 joules.
