energy and respiration

describe the need for energy ....some help pleaseeeeee
Organisms need energy for... pretty much everything, actually. Think seven life processes, movement, growth/repair, reproduction etc.

Basically, energy released from respiration is used to drive the chemical reactions needed to keep organisms alive such as the reactions to build complex carbohydrates , proteins and lipids from the products of photosynthesis in plants, and the products of digestion in animals.
