Freshwater wetlands dominated by emergent herbaceous vegetation are called ________.

Mangrove swamps

Riverine wetlands usually have a longer hydroperiod than basin wetlands.

Outline the interacting components that have led to the degradation of the Coote's Paradise Marsh in Lake Ontario. Can it recover?

Mangrove forests function as a bioshield. What does this mean?

Most organisms in the intertidal zone of sandy shores burrow into the sand.

________ forests typically grow in the intertidal zone of tropical coasts where wave action is absent, sediments accumulate, and the muds are anoxic.

Describe the effects of tides on the composition of animal communities in salt marshes.

The initial factor which set about the decline of Coote's Paradise Marsh in Lake Ontario was ________.

In comparison to rocky coasts, intertidal organisms living on sandy or muddy beaches

The diversity of organisms is greater in the intertidal zone of rocky shores than in sandy and muddy shores.

Name three ecological zones within a rocky shore and discuss the different forms of life that occur in each.
