    No.

    Becuase they could go at both ends. Their exact position can't really be

    pinpointed, since they could go in at any point.The decomposer would supply nourishment to, say, grass. Then that grass would be eaten by a rabbit or some

    herbivore/ omnivore, which might get eaten by a carnivore. But when the carnivore dies, the decomposer would come back into the equation and break down the carnivore, thus giving to the grass or other vegetation, creating a loop. Also, the decomposer could come in at any point should any other link die; the decomposer would just break it down again. In conclusion, the decomposer breaks down ANY dead things, whether producer or any level consumer. It can also give nourishment to plants, so it can go in anywhere. It's simpler not to include a decomposer.

    No.

    Food chain shows the feeding relationship and energy flow in which energy is lost in every levels.

    Even though decomposers help decompose matter and return the locked energy to the environment, they are not included in food chain.
