Which term refers to the capacity to do work or drive biological processes?

• A. Entropy
• B. Evolution
• C. Food
• D. Energy

Answer: (D)

Energy is the capacity to do work or drive biological processes. In living systems, energy powers metabolism, growth, transport across membranes, and movement, and it exists in chemical forms such as ATP and other molecules. A source like food provides this energy by being metabolized, but the term that describes the capacity to do work itself is energy. Entropy relates to disorder and the direction of energy spread, not to the ability to perform work; evolution is about changes in genetic composition over time; food is a source of energy rather than the capacity itself.
