Answer
The difference between a grazing food web and a detrital food web is as follows: a grazing food web begins with photosynthetic producers (trees, shrubs, grass), while a detrital food web begins with decomposers (including bacteria, fungi, and earthworms).
An example of a grazing food chain is as follows:
Leaves --> caterpillars --> mice --> hawks
An example of a detrital food chain is as follows:
Detritus --> earthworms --> beetles --> shrews
