What coastal ecosystems are among the most productive?

Estuaries. Estuaries, places where rivers meet the sea, are among the most productive environments for supporting commercial fisheries around the world and are vital to the economy. This makes the protection and restoration of these complex ecosystems particularly important.

Why are coastal ecosystems so important to ocean life?

Coastal and estuarine ecosystems deliver a wide range of goods and services, many of which provide material benefits such as food supply, regulation of water-quality processes, storm protection, and carbon storage.

What factors are necessary for the most productive marine ecosystem?

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

What factors contribute to the productivity of estuaries?

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. Wetlands that fringe many estuaries also have other valuable functions.

Why coastal waters are more productive than the open ocean?

Coastal waters are more productive than the central ocean for two main reasons. First, runoff from land often contains a high abundance of nutrients which get deposited in coastal waters and stimulate production.

What part of the ocean is the most productive and why?

Although they occupy less than two percent of the oceans, the coastal upwelling areas in the eastern parts of the Pacific and Atlantic Ocean are among the biologically most productive marine areas worldwide. They not only support a large biodiversity, but also provide 20 percent of the world’s fish harvest.

How does coastal habitats affect the ecosystem?

The disappearance of these ecosystems, which include coral reefs, mangrove forests, wetlands and seagrass meadows, has serious consequences like loss of biodiversity, depletion of exploitable living resources, impaired capacity of the oceans to sequester carbon dioxide and loss of the leisure value of the coastal zone.

How does a coastal ecosystem work?

Coastal ecosystems deliver a range of ecological services that support the Reef, including water distribution, food and habitat, and nutrient and chemical cycling. For example, many reef species use the catchment for some of their life cycle.

What is the importance of marine ecosystem?

Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.

Why does the ocean have low productivity?

In ocean, sunlight is the main limiting factor which decreases the rate of photosynthesis. … Minerals and nutrients can also be a retarding factor based on location of the oceans.So, there will be less productivity than land which is 170 billion tons compared to 55 billion tons ion oceans.
