In an ecosystem, which option shows oneway passage?
Correct answer: A. Free energy
- A. Free energy
- B. Carbon
- C. Nitrogen
- D. Potassium
Explanation
The behavior of energy in an ecosystem can be termed as energy flow due to the unidirectional flow of energy. The flow of energy is only in one direction i.e., from solar radiation - producers -herbivores - carnivores. This energy cannot pass in the reverse direction. There is a decrease in the content and flow of energy with a rise in trophic levels.
