Question

Which of the following statements is an important consequence of the first law of thermodynamics for a living organism? The energy content of an organism is constant. Organisms grow by converting energy into organic matter. An organism ultimately must obtain all of the necessary energy for life from its environment. The entropy of an organism decreases with time as the organism grows in complexity.

Answer 1

An organism ultimately must obtain all of the necessary energy for life from its environment

Answer 2

Answer:

An organism ultimately must obtain all of the necessary energy for life from its environment.

Explanation:

The First Law of Thermodynamics is also known as the law of conservation of energy. This law states that energy can neither be created nor destroyed, it only can change its form. The energy in a closed system remains constant.

All the organisms require energy to perform their life processes. The ultimate source of energy is the sun.  The energy is supplied by the sun is used by green plants to synthesise food (glucose), chemical energy. Thus, light energy is converted to chemical energy. The chemical energy is transferred to animals through food chains.
