Question
Energy transfers within food webs are governed by only the second law of thermodynamics.
- True
- False
Hint:
The first and second principles of thermodynamics control the energy exchanges that take place within food webs.
The correct answer is 'False'.
The correct answer is, that it is governed by both laws.
- According to the First Law, an energy budget can account for all energy exchanges, gains, and losses within a food web. The second rule of thermodynamics governs all energy transformations. It simply asserts that energy is lost every time it is changed because heat is released. Similar to how it does in a food chain or food web, energy is lost as heat is transported between trophic levels.
- As a result, energy in an ecosystem flows in only one direction.
