Question

In the food web, which is the correct flow of energy?

  1. DCA
  2. ACD
  3. BAF
  4. ACF

hintHint:

The ecosystem will only remain in balance if the flow of energy is linear and unidirectional, without any break in between.

The correct answer is: ACF


    • The correct flow of energy as per the figure is ACF.
    • The flow of energy in an ecosystem is unidirectional. It moves from one organism to another. 
    • As given, A will act like a producer which makes its own food, called autotrophs. 
    • C will act like a first-level consumer, also known as a primary consumer, and will feed on A.
    • F here will act like a third-level consumer or tertiary consumer which in return will consume C for its survival.

    The energy passed from one tropic level to another never comes back to the lower levels.

    Which food might a first-level consumer eat?

    Usually, in a food chain, producers are eaten by first-level consumers, Those are then consumed by second-level consumers, and so on. This chain continues in this form and at one point, decomposers feed on these consumers and decompose them.

    _________ flows through a food web/chain and powers each organism at every trophic level.

    The food chain ensures a unidirectional flow of energy through the ecosystem, that is, from one tropic level to another. Also, energy flow decreases with each tropic level.
