Q1) True

Q2) Metabolism

Q3) Physiological response

Explanation:

Q1) Energy cannot be created (first law of thermodynamics). Life needs an energy source to transform. Without the energy from the sun or any other sources, life would cease to exist. (True)

Q2) An organism chemical reactions consist, in general, breaking down complex molecules (catabolism) releasing energy or to form complex structures from simpler molecules (anabolism) which require energy . The total of this reactions is called metabolism.

Q3) Hibernation is physiological state of inactivity and metabolic depression in some organisms, which result as a response to low temperatures and unavailability of food.
