What are the 3 ecosystem services?

More About Ecosystem Services

  • Provisioning Services or the provision of food, fresh water, fuel, fiber, and other goods;
  • Regulating Services such as climate, water, and disease regulation as well as pollination;
  • Supporting Services such as soil formation and nutrient cycling; and.

What are the 10 services provided by ecosystems?

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.

  • It provides an environment for producers to trap sun’s energy and provide food.
  • It is responsible for the cycling of nutrients between biotic and abiotic components.

Organism is considered as the functional unit of ecology.

What is the functional component of ecosystem?

Hint: An ecosystem is defined as the functional unit of nature in which living organisms live and interact within themselves as well as the abiotic factors of their environment. Trophic level is associated with energy flow between producers, consumers, decomposers, etc.

What are 5 examples of ecosystem services?

Some examples include biomass production, production of atmospheric oxygen, soil formation and retention, nutrient cycling, water cycling, and provisioning of habitat.

What are the 5 categories of ecosystem services?

Terms in this set (5)

  • Provisions. Good produced by ecosystems that humans can use directly.
  • Regulating services. Help regulate environmental conditions i.e. amount of carbon dioxide in air.
  • Support services. Support sources that would be costly for humans i.e. pollination of plants.
  • Resilience. …
  • Cultural services.
