Negative entropy refers to:

• A. Exchange of energy that promotes growth
• B. Disorder increasing over time
• C. A closed, isolated system
• D. Random fluctuations with no effect

Answer: (A)

Negative entropy, or negentropy, is the process by which a system maintains or increases order by importing energy and information from its surroundings. This energy flow fuels growth, structure, and self-organization, allowing living and organized systems to counteract the natural drift toward disorder.

That’s why the description of energy exchange that promotes growth best fits. When a system receives energy, it can build and sustain ordered patterns and functions. In contrast, entropy rising over time describes increasing disorder, not negentropy. A closed, isolated system lacks external energy input, so it cannot generate sustained negentropy, and random fluctuations with no lasting effect do not create enduring order.
