\nThe correct answer is Metabolism. Metabolism encompasses all the chemical processes that occur within a living organism to maintain life, including those that generate energy.
\n<\/section>\n
\nMetabolism includes catabolic pathways which break down complex molecules (like carbohydrates, fats, proteins) obtained from food, releasing energy in the process (primarily in the form of ATP) that is used for cellular activities and maintenance of life.
\n<\/section>\n
\nPhagocytosis is a process of engulfing particles; Photorespiration is a process in plants that reduces photosynthetic efficiency; Decomposition is the breakdown of dead organic matter. While these processes are related to obtaining or releasing energy in specific contexts, Metabolism is the general term for the sum of biochemical reactions within an organism that yield energy for life functions.
