Show a wetland food chain in Ontario?

A wetland food chain in Ontario might start with aquatic plants like cattails and bulrushes, which serve as primary producers. These plants are consumed by herbivores such as snails and frogs. In turn, these herbivores are preyed upon by secondary consumers like turtles and wading birds, such as herons. Finally, top predators like otters or large fish, such as pike, may feed on these secondary consumers, completing the food chain.
