Question

Which food might a first-Three organisms on the food web have arrows pointing toward them but no arrows pointing away from them. This is because level consumer eat?

  1. They make their own food   
  2. Nothing shown eats them
  3. They give energy to others  
  4. They need no energy

hintHint:

The direction of the arrow indicates the flow of energy from one organism to another.

The correct answer is: Nothing shown eats them


    • In a food chain or food web, If there are arrows pointing toward them but no arrows pointing away from them then it means that nothing shown eats them.
    • In a food chain, the arrows suggest that a particular organism is being consumed by the one to whom the arrow is pointing. This means, that the net flow of energy is in that direction. 
    • Decomposers are the ones that are not consumed by any other organism, instead, they are the ones consuming each one of them. And thus, all arrows point towards them. 

    Decomposers are organisms that have the ability to break down or decay the dead organisms. They are a critical part of the ecosystem.

    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.
