The flow of energy through various trophic levels in an ecosystem is unidirectional and non-cyclic. Explain.
Answers (1)
About 90% of the energy consumed by an organism at a particular trophic level is dissipated in the form of heat energy. This leaves just 10% for the organism at the next trophic level. By the time, it reaches the topmost trophic level; the available energy is an extremely small portion of the energy, which was originally converted by the producer. Due to this, energy flow is unidirectional through various trophic levels and is non-cyclic.
