Many different types of plant and animal communities call estuaries home because their waters are typically brackish — a mixture of fresh water draining from the land and salty seawater. This unique combination of salty and fresh water creates a variety of habitats.

Why can estuaries support a lot of plant and animal life?
Estuaries are full of decaying plants and animals. This makes the soil of estuaries rich in nutrients. Because the soil is so rich, lots of different plants grow in estuaries. The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary.
Why do estuaries have high productivity?
Estuaries are one of the most productive ecosystems on earth. They maintain water quality through natural filtration as microbes break down organic matter and sediments bind pollutants. ... Water draining from the land carries sediments, nutrients, and other pollutants.
Why are plants important in estuary?
They provide coastal buffers from storm surge and flooding. Plants in estuarine habitats also hold onto sediments to decrease erosion and loss of shoreline. These plants and shellfish such as oysters, clams, and muscles help filter pollutants from the water.
What plants and animals live in estuaries?
These habitats can include oyster reefs, coral reefs, rocky shores, submerged aquatic vegetation, marshes, and mangroves. There are also different animals that live in each of these different habitats. Fish, shellfish, and migratory birds are just a few of the animals that can live in an estuary.
Why are estuaries important to animals?
Because they are biologically productive, estuaries provide ideal areas for migratory birds to rest and refuel during their long journeys. Because many species of fish and wildlife rely on the sheltered waters of estuaries as protected spawning places, estuaries are often called the "nurseries of the sea."
Why are estuaries and intertidal zones important to living and nonliving things?
Estuaries support a diversity of species of fish, shellfish, aquatic plants and animals. The protected waters provide vital nesting, breeding and feeding habitats for many species. Estuaries also filter pollutants out of the water flowing through them, including pesticides, herbicides and heavy metals.
Why are estuaries more productive than most other biomes?
Why are estuaries more productive than other biomes? Estuaries have shallow, nutrient laden water.
How do plants and animals interact with each other in an estuarine ecosystem?
Plants (such as phytoplanktonalgae, seagrass, salt marsh and mangroves) take up nutrients, which are then eaten by animals. When the plants and animals die and decompose, the nutrients are released again. Organisms such as fish and birds transfer nutrients as they move in and out of the estuary.
How do estuaries promote the growth of plants?
In some parts of estuaries, filtered by plants such as marsh and seagrasses, moving water becomes still, allowing mud and food particles to settle at the bottom. These variations create safe conditions, making estuaries ideal homes for plants and animals who feed, grow, or reproduce there.
How do animals survive in estuaries?
In almost all estuaries the salinity of the water changes constantly over the tidal cycle. To survive in these conditions, plants and animals living in estuaries must be able to respond quickly to drastic changes in salinity. Plants and animals that can tolerate only slight changes in salinity are called stenohaline.
How many animals live in estuaries?
There are more than 200 species of fish that live in estuary waters. In the Pacific Northwest, salmon migrate through estuaries and upriver to breed and spawn.
How do plants adapt to estuaries?
PLANTS: Plants found in estuaries need to be adapted to salty conditions. ... Some plants, like pickle weed, can absorb the salt water and store the salt in special compartments, called vacuoles, in the leaves. This makes the plant taste very salty which may be one of the reasons it is called pickle weed.
Why are estuaries and wetlands important?
Estuaries and their surrounding wetlands are also buffer zones. They stabilize shorelines and protect coastal areas, inland habitats, and human communities from floods and storm surges from hurricanes.
Why are estuaries and intertidal zones important?
Why Is the Intertidal Zone Important? The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals. Those organisms, in turn, serve as food for many other animals.
