This refers to the continuous supply of energy required by living organisms to perform various life processes, such as growth, reproduction, and maintenance.
Think of constant energy input like a car's fuel. Just as a car needs a steady supply of gas to keep running smoothly, an organism needs a constant input of energy to carry out its functions.
Metabolism: The chemical processes that occur within a living organism in order to maintain life.
Photosynthesis: The process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Cellular Respiration: A set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
