Aquatic Zones

&<–2/”>a >nbsp;

Aquatic systems are not called biomes,

The major differences between the various aquatic zones are due to salinity, levels  of dissolved nutrients; water temperature, depth of sunlight penetration.

 

  1. Fresh Water Ecosystem-Fresh water ecosystem are classified as lotic

(moving water) or lentic (still or stagnant water).

 

  1. Marine Ecosystem-
  2. Estuaries-Coastal bays, river mouths and tidal marshes  form  the

estuaries.  In estuaries, fresh water from rivers meet ocean water and the two are mixed by action of tides.

Estuaries are highly productive as compared to the adjacent river or sea,

Aquatic zones are areas of the Earth’s surface that are covered by water. They include freshwater lakes, rivers, and wetlands, as well as marine environments such as the ocean, coastal zones, and the deep sea.

Freshwater lakes are bodies of water that are not connected to the ocean. They can be found on every continent, and they range in size from small ponds to large lakes such as Lake Superior. Freshwater lakes are important Ecosystems that provide habitat for a variety of Plants and animals. They also play a role in the water cycle, and they are a source of drinking water for humans and other animals.

Rivers are flowing bodies of water that transport water from one place to another. They can be found on every continent, and they range in size from small streams to large rivers such as the Amazon River. Rivers are important ecosystems that provide habitat for a variety of plants and animals. They also play a role in the water cycle, and they are a source of water for Irrigation, drinking, and transportation.

Wetlands are areas of land that are saturated with water, either permanently or seasonally. They include marshes, swamps, and fens. Wetlands are important ecosystems that provide habitat for a variety of plants and animals. They also play a role in the water cycle, and they help to filter pollutants from water.

The ocean is the largest aquatic zone on Earth. It covers about 71% of the Earth’s surface, and it is home to a vast array of plants and animals. The ocean plays a vital role in the Earth’s Climate, and it is a source of food, water, and Minerals for humans.

Coastal zones are areas where the land meets the ocean. They include estuaries, lagoons, mangrove swamps, and salt marshes. Coastal zones are important ecosystems that provide habitat for a variety of plants and animals. They also play a role in the water cycle, and they help to protect the coast from erosion.

The open ocean is the vast area of water that lies beyond the coastal zones. It is home to a variety of plants and animals, including fish, whales, and dolphins. The open ocean plays a vital role in the Earth’s climate, and it is a source of food, water, and minerals for humans.

The deep sea is the area of the ocean that lies below the continental shelf. It is a vast and largely unexplored region, and it is home to a variety of plants and animals that have adapted to the extreme conditions of the deep sea. The deep sea plays a vital role in the Earth’s climate, and it is a source of food, water, and minerals for humans.

Aquatic zones are essential to the Earth’s ecosystems, and they provide a variety of benefits to humans. It is important to protect these vital ecosystems from pollution and other threats.

What is the difference between freshwater and saltwater?

Freshwater is water that contains less than 1% salt, while saltwater contains more than 35% salt. Freshwater is found in lakes, rivers, and streams, while saltwater is found in Oceans and seas.

What are the different types of aquatic ecosystems?

There are three main types of aquatic ecosystems: freshwater, saltwater, and marine. Freshwater ecosystems include lakes, rivers, and streams. Saltwater ecosystems include oceans and seas. Marine ecosystems include coral reefs, estuaries, and mangrove forests.

What are the different types of aquatic organisms?

There are many different types of aquatic organisms, including fish, shellfish, algae, and plankton. Fish are vertebrates that live in water. Shellfish are invertebrates that have a hard shell. Algae are simple plants that live in water. Plankton are tiny organisms that float in water.

What are the threats to aquatic ecosystems?

There are many threats to aquatic ecosystems, including pollution, overfishing, and Climate Change. Pollution can come from many sources, including factories, farms, and cars. Overfishing is when too many fish are caught. Climate change can cause sea levels to rise and ocean temperatures to increase.

What can we do to protect aquatic ecosystems?

There are many things we can do to protect aquatic ecosystems, including reducing pollution, practicing sustainable fishing, and conserving water. We can also support organizations that are working to protect aquatic ecosystems.

What are the benefits of aquatic ecosystems?

Aquatic ecosystems provide many benefits, including food, water, and recreation. They also help to regulate the climate and protect coastlines from erosion.

What is the future of aquatic ecosystems?

The future of aquatic ecosystems is uncertain. If we do not take steps to protect them, they may be lost forever. We need to work together to reduce pollution, conserve water, and sustainably manage our Fisheries-2/”>Fisheries.
