Forest ecosystems allow for provisioning services for humans such as timber for fuel or building, as well as paper. One human impact that can degrade this ecosystem service is deforestation. Deforestation removes a significant amount of trees from the ecosystem thus removing the impact of this service to humans.

Where do you get your cool slide backgrounds?

I found an AP Practice question on AP Classroom that classified pollinators are 'regulating' resources not supporting resources. Which one is actually correct? Or are they both?

[patsedits]

JUST FYI: united nations food and agriculture organization classifies pollination as a regulating service. according to this… the statement made in the video is false. thank you for your content sir.

Forests provide humans with oxygen, through photosynthesis. Farmers along the Amazon forest, have been illegally cutting trees and plants, to have more space for cattle grazing and crop planting. This deforestation kills the trees, stopping them from doing photosynthesis, and therefore decreasing the amount of oxygen released into the atmosphere.

The definition of supporting ecosystem service given in this video is not consistent with the definition of the UN FAO, the USDA, the National Wildlife Federation, the AP classroom video on this topic or any other source I can find. Other sources consistently state that supporting ecosystem services are services upon which the other three categories of ecosystem services depend. They differ from the other ecosystem services in that they impact humans indirectly through the other services and typically act over long time frames. Examples include: providing habitat, soil formation, biomass formation, oxygen production, and nutrient cycling. The UN FAO classifies waste water treatment and pollination as regulating services, not supporting services.

Please take the time and put Spanish closed captioning. You are missing out, and we are too.
