Energy flow in an ecosystem is _____ .
Open in App
Solution
The correct option is C Unidirectional
The driving force for the ecosystem is the energy of the sun. The autotrophs capture the solar energy and convert it into food. The energy harnessed by the primary producers, flows from producers to consumers to decomposers and at each trophic level some energy dissipates as heat. Once the energy is lost as heat, it cannot be recycled. Hence, we say that energy flow in an ecosystem is unidirectional.
