Multiple Choice

Organisms are described as thermodynamically open systems. Which of the following statements is consistent with this description?

The metabolism of an organism is isolated from its surroundings.

Because energy must be conserved, organisms constantly recycle energy and thus need no input of energy.

Heat produced by the organism is conserved in the organism and not lost to the environment.

All of the listed responses are correct.

Organisms acquire energy from and lose energy to their surroundings.

Verified step by step guidance

Understand the concept of thermodynamically open systems: These systems exchange both energy and matter with their surroundings, unlike closed systems which do not exchange matter.

Consider the role of metabolism in organisms: Metabolism involves chemical reactions that transform energy and matter, indicating interaction with the environment.

Evaluate the statement about energy conservation: While energy is conserved in a closed system, organisms are open systems and require a continuous input of energy from their surroundings.

Analyze the statement about heat conservation: In open systems, heat is not conserved within the organism but is exchanged with the environment.

Conclude with the correct description: Organisms acquire energy from and lose energy to their surroundings, consistent with being thermodynamically open systems.
