What is the main meaning of life processes?
Answer and explanation
Correct answer: Activities that maintain life in organisms
Life processes are the essential activities that keep an organism alive and functioning. They include nutrition for obtaining materials and energy, respiration for releasing usable energy, transportation for distributing substances, and excretion for removing wastes. Therefore option A gives the broad and correct meaning. Changing colour, moving outside, or sleeping may occur in some situations, but none of these alone defines life processes.
