Estuaries support many marine organisms because estuaries receive plenty of light for photosynthesis and plenty of nutrients for plants and animals. Rivers supply nutrients that have been washed from the land, and because the water is shallow, sunlight can reach all the way to the bottom of the estuary.

What are the food base of most aquatic ecosystems?
Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

How many of the world’s 10 largest urban areas are built on estuaries and what concerns might this cause for wildlife?
Estuaries provide protected harbors, access to the ocean, and connection to a river. As a result, many of the world’s major ports are built on estuaries. Of the 10 largest urban areas in the world, 6 were built on estuaries. These 6 cities are Tokyo, New York Shanghai, Buenos Aires, Rio de Janeiro, and Bombay.

What are the main limiting factors of aquatic organisms?
Most aquatic organisms do not have to deal with extremes of temperature or moisture. Instead, their main limiting factors are the av ailability of sunlight and the concentration of dissolved oxygen and nutrients in the water.

What is a decomposer in an aquatic ecosystem?
Decomposers, which include bacteria, fungi, and other microorganisms, are the other major group in the food web. They feed on the remains of all aquatic organisms and in so doing break down or decay organic matter, returning it to an inorganic state.

What is a food chain aquatic ecosystem?
The food chain in an aquatic habitat often starts with algae or phytoplankton as producers, followed by zooplankton that eats them. Giant fish, sharks, and whales consume zooplankton, which is eaten by small fish and crustaceans. A water-based food chain is known as an aquatic food chain.

What makes up an aquatic ecosystem?
Aquatic ecosystems include oceans, lakes, rivers, streams, estuaries, and wetlands. Within these aquatic ecosystems are living things that depend on the water for survival, such as fish, plants, and microorganisms. These ecosystems are very fragile and can be easily disturbed by pollution.

What factors affect aquatic organisms?
What factors affect life in aquatic ecosystems? Aquatic organisms are affected primarily by the water’s depth, temperature, flow, and amount of dissolved nutrients. Water depth strongly influences aquatic life because sunlight penetrates only a relatively short distance through water.

What limits aquatic ecosystems?
Phosphorus is usually considered the “limiting nutrient” in aquatic ecosystems, meaning that the available quantity of this nutrient controls the pace at which algae and aquatic plants are produced. In appropriate quantities, phosphorus can be used by vegetation and soil microbes for normal growth.

Of the 10 largest urban areas in the world, 6 were built on es- tuaries. These 6 cities are Tokyo, New York, Shanghai, Buenos Aires, Rio de Janeiro, and Bombay. Estuaries in populated areas were often used as solid waste landfills.

How would building a city on an estuary affect the plants and animals living in an estuary?
Estuaries provide protected harbors, access to the ocean, and connection a river which makes it ideal for building port cities on. This can affect the plants and animals living in the estuary because pollutants will enter into the estuary corrupting its nutrient rich mud.

Which is a potential threat to an estuary?
The greatest threat to estuaries is, by far, their large-scale conversion by draining, filling, damming, or dredging. These activities result in the immediate destruction and loss of estuarine habitats.

What are examples of aquatic decomposers?
These can include lobsters, shrimp, clams, mussels. Like the echinoderms, crustaceans and molluscs are also known as macro decomposers. They feed on decaying matter to help add nutrients to the ocean ecosystem.
