What does the overall study of life processes explain most effectively?
Answer and explanation
Correct answer: Organisms maintain life by regulating materials and energy
Life processes collectively explain how organisms obtain nutrients and oxygen, release usable energy, transport materials, regulate internal conditions and remove wastes. These activities maintain the material and energy balance needed for survival. Thus option A is correct. Size alone cannot sustain life, wastes are produced by metabolism, and multicellular organisms require transport systems.
