Explanation:

The energy flow in an ecosystem is unidirectional and non-cyclic.
The energy flow takes place via food chain and food web. Thus, the plants being the producers harness the energy from the sun in the process of photosynthesis. This energy is passed on to the primary consumers in the food chain, followed by the secondary consumers and finally to the tertiary consumers. Thus, the energy flow is unidirectional in nature.
