ABSTRACT
An ecosystem contains two chief types of food webs: a grazing food web (plants, herbivores, carnivores, top carnivores) and a decomposer or detrital food web (Figure 6.7).
This simple feeding sequence
plant ® herbivore ® carnivore ® top carnivore
is a grazing food chain. An example is
leaf ® caterpillar ® bird ® weasel.
