Why are life processes necessary?
Answer and explanation
Correct answer: For survival
The governing concept is maintenance of life. Every organism needs energy, nutrients, transport of materials and removal of harmful metabolic wastes. Nutrition, respiration, transportation and excretion perform these functions and keep cells working. Growth may result from life activities, but it is not their only purpose; colour change and stopping movement are unrelated. Thus option A is correct.
