Question
Flow of energy in an ecosystem is always
Options
unidirectional
bidirectional
multi directional
no specific direction
Solution
unidirectional
Explanation -
In an ecosystem, the autotrophs capture the energy present in sunlight and convert it into chemical energy. So, energy flows from Sun to the autotrophs. From autotrophs, the energy goes to the herbivores and decomposers. From, herbivores, the energy is passed on to the organisms of the next trophic level and so on but it never flows backwards. So, the flow of energy in an ecosystem is always unidirectional.
