Question: Which of the following are ecosystem services provided by salt marshes?

Among coastal ecosystems, salt marshes provide a high number of valuable benefits to humans, including raw materials and food, coastal protection, erosion control, water purification, maintenance of fisheries, carbon sequestration, and tourism, recreation, education, and research.

Why salt marshes are important to the ecosystem?

Salt marshes certainly play a critical role in the aquatic food web, but they can also protect cities and towns from coastal flooding by absorbing the influx of water during storm surges and providing buffers between the sea and homes and businesses.

What are the 4 ecosystem services?

Four Types of Ecosystem Services

The Millennium Ecosystem Assessment (MA), a major UN-sponsored effort to analyze the impact of human actions on ecosystems and human well-being, identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services.

What do salt marshes provide for humans?

What are 5 examples of ecosystem services?

More About Ecosystem Services

  • Provisioning Services or the provision of food, fresh water, fuel, fiber, and other goods;

  • Supporting Services such as soil formation and nutrient cycling; and.

What are the 24 ecosystem services?

Regulating services

  • Purification of water and air.
  • Carbon sequestration and climate regulation.
  • Waste decomposition and detoxification.
  • Predation regulates prey populations.
  • Biological control pest and disease control.
  • Pollination.
  • Disturbance regulation, i.e. Flood protection.

What are the five ecosystem services?

The benefits ecosystems provide include food, water, timber, air purification, soil formation and pollination. But human activities are destroying biodiversity and altering the capacity of healthy ecosystems to deliver this wide range of goods and services.

What is a salt marsh ecosystem?

Salt marshes are coastal wetlands rich in marine life. They are sometimes called tidal marshes, because they occur in the zone between low and high tides. … Salt marsh plants cannot grow where waves are strong, but they thrive along low-energy coasts.

Is a salt marsh a top down or bottom up ecosystem?

Abstract. Traditionally, salt marsh ecosystems were thought to be controlled exclusively by bottom–up processes. Recently, this paradigm has shifted to include top–down control as an additional primary factor regulating salt-marsh community structure.
