A caterpillar eats grass and is then eaten by a mouse. A hawk eats the mouse, then dies and is decomposed by mushrooms.

Explanation:

A trophic chain might be composed of producers (Grass or trees), primary consumers that are herbivores (Locust or Squirrel), secondary consumers that are carnivores (mouse or eagle), and decomposers (fungi).

-------------------------------------------

When talking about the trophic web, we refer to the energy transference from one organism to the other. These organisms place at different levels. Each level feeds on the anterior one and gets eaten by the next one.

  • The first link is composed of organisms that take radiation energy to produce organic compounds. These are autotroph organisms or producers.
  • The following links are the consumers:

primary consumers are herbivores and feed on producers.

secondary consumers are carnivores that feed on herbivores.

tertiary consumers are also carnivores, and feed on secondary consumers, and so on.

  • The last links are the decomposers. These are fungi and microorganisms that act on dead animals degrading organic matter.

Any change that occurs at any of the links will immediately affect the other links too. It will cause an increase or decrease in their population sizes.

In the exposed trophic web, we can recognize two complete chains.

         Producer        1º consumer       2º Consumer         Decomposer

  1.  Grass     ⇒         Locust       ⇒        Mouse      ⇒           Fungi
  2.    Tree     ⇒         Squirrel      ⇒        Eagle       ⇒           Fungi
