Hemingway Name: Pond Succession Sand Dune Succession Micro organisms carried by wind and insects are deposited in the water. Micro organisms die and form a layer of muck on the pond bottom Water plant fragments transported by birds and wind take root in the muck The increase in decaying organism create more organic matter on the pond bottom in which cattails and lilies take root Water lilies and cattails die off creating more organic matter Water becomes shallower, grasses and small shrubs move in Fish and other animals carried by streams, birds or other animals move in Nutrients obtained from decaying seaweed Decaying vegetation create soil Soil can hold water so lichens and mosses can grow Grasses that can tolerate salt spray from the ocean can grow Grasses help anchor the soil Shrubs can grow because of a increased amount of soil A forest of white spruce eventually grows Hemingway Name: Hemingway Name:
