Why is energy needed for life on Earth?
Organisms use the stored energy in food to fuel all living processes. Food is organic molecules that serve as fuel and building material for all organisms. The breakdown of food molecules enables cells to store energy and to carry out the many functions of the cell and therefore the entire organism.
Why is energy and matter important?
Energy and Matter are essential concepts in all disciplines of science and engineering often in connection with systems. “The supply of energy and of each needed chemical element restricts a system’s operation—for example without inputs of energy (sunlight) and matter (carbon dioxide and water) a plant cannot grow.
