Laws of Life: Thermodynamics in Biology Quiz

Apply the laws of physics to living things in this thermodynamics in biology quiz. Study how the flow of energy through the biosphere follows the rules of entropy, requiring a constant input of solar energy to maintain the...

Questions: 15 | Attempts: 17 | Last updated: Mar 9, 2026

Sample Question 1
Which law of thermodynamics states that energy cannot be created or destroyed, only transformed within an ecosystem?

First Law

Second Law

Third Law

Law of Conservation of Mass

Sample Question 2
Why is the transfer of energy between trophic levels never 100% efficient according to the Second Law of Thermodynamics?

Energy is converted into matter

Entropy increases as heat is released

Producers reflect most of the energy

Predators use more energy than prey

Sample Question 3
Living organisms are "closed systems" that do not exchange energy or matter with their surroundings.

True

False
