Organisms are described as thermodynamically open systems. Which of the following statements is consistent with this description?
A
The metabolism of an organism is isolated from its surroundings.
B
Because energy must be conserved, organisms constantly recycle energy and thus need no input of energy.
C
Heat produced by the organism is conserved in the organism and not lost to the environment.
D
All of the listed responses are correct.
E
Organisms acquire energy from and lose energy to their surroundings.

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.
