Living things have structures known as cells, they grow and exhibit movement or locomotion. They experience metabolism which includes anabolic and catabolic reactions. Living things are capable of producing a new life which is of their own kind through the process of reproduction. Living things have a particular life span and are not immortal. Cellular Respiration¬†enables living organisms to acquire energy which is used by cells to perform their functions. They digest food for energy and also excrete waste from the body. Their life cycle can be summarised as… Read More
