    The reason is because detritivores and decomposers and omnivores are multilevel food chain consumers in an ecosystem making them not qualified to be assigned to a given trophic level

    Explanation:

    An organism is placed in a trophic level based the level it is from where the food chain starts with the start of the food chain having a level of 1 for the food producers such including plants and algae

    Level 2 organisms are called primary consumers and consists of organism that eat only plants known as herbivores such as cattle

    Level 3 organisms are called secondary consumers and consists of animal eating organism known as carnivores such as foxes etc.

    Level 4 organisms are called tertiary consumers

    Level 5 organisms are the a p e x p r e d a t o r s

    Detritivores and decomposers such as bacteria, earthworm flies fungi consume the wastes produced at all trophic levels, therefore they cannot be assigned to a particular trophic level

    Similarly, omnivores consumes both plants at level 2 and animals at level 3 making it ambiguous to assign them to one particular trophic level.
