Question 10
The flow of energy in an ecosystem is always
(a) unidirectional
(b) bidirectional
(c) multi directional
(d) no specific direction
Option (a) is correct.
Flow of energy is unidirectional, plants absorb energy from the sun, convert it into food, herbivores eat plants and energy transfer takes place. Carnivores eat herbivores and so on, the energy gets transferred, but the vice versa does not take place.
