26.Estuaries Notes Day 2 EQ: What are the different aquatic ecosystems? Why are they so important to life on Earth? LT: I can identify various aquatic ecosystems & their important features. POU: I will describe Estuaries and their importance as a diverse ecosystem. I will define and explain the importance of a wetland.

What does an estuary look like from a satellite vs a helicopter? Ocean Brackish Fresh
Protective Environment Estuaries help control erosion & reduce flooding. 1. Sand bars buffer impact of waves 2.Plants and shell fish beds anchor the shore against tides. Swamps and marshes take the initial impact of high winds moving in from the ocean, soak up heavy rain and storm surges, and release the extra the extra water gradually into river and groundwater supplies.
Protective Environment 1. Because estuaries are shallow (less than 30 ft deep) sunlight penetrates all the way to the bottom. This promotes plant growth. 2. Rivers feed estuaries sediments rich in nutrients, which settle onto the sand and mud of the estuary floor. These unique conditions create biodiversity in species of (fish, shrimp, crabs, clams, and oysters) that adapt the brackish conditions.
Estuaries are great Nurseries! Estuaries are also good nurseries as they provide a protected environment for species to hatch and grow in before they migrate to the sea to live out their adult lives.
Nurseries Estuaries act as “Nurseries” for marine and aquatic species. – Marine – Live in ocean – Aquatic – Live in water Fish will lay eggs in estuaries – Safe from ocean predators – Calmer, more nutrient rich water
Resting and Breeding Ground Birds depend on the estuary for resting and feeding Lots to eat Crabs, worms, clams, and more live in the muddy areas.

Wetlands 16 What is a wetland? – An area where the water table is at, near or above the land surface long enough during the year to support adapted plant growth What are the types of wetlands? – Swamps, bogs, and marshes Swamp: a wetland dominated by trees Bogs: a wetland dominated by peat moss Marshes: a wetland dominated by grasses

Wetlands 16 Why are they important? 1.Help prevent Flooding by absorbing excess water 2.Help prevent erosion 3.Help filter water flowing through it
