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?
Hey Christie, the classification of certain ecosystem services is always a point of contention for APES students and teachers. I usually teach pollinators as a supporting service in their role as pollinators of commercial crops, as they are supporting human agriculture. They could probably be classified as a regulating service if you consider the role they play in supporting biodiversity of native plant species that rely on them as pollinators as well. Overall, I always tell students its more important to understand HOW ecosystem services provide monetary value to humans and how we disrupt them than to memorize examples of the categories. Hope this helps!
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.
Hi Simon, In eight years of teaching environmental science I've always found the boundary between supporting and regulating services difficult to distinguish and less important for students to get hung up on than the overall concept of understanding how ecosystems provide financially valuable services to humans and how our actions can degrade the value of these services. That being said, I still try to always present information in my videos as accurately as possible. If you consult Friedland & Relyea Environmental Science for AP, which many APES teachers use, you'll see that the authors classify both pollination and water filtration as support services using a definition of supporting services similar to how I present them in this video. I poked through a few of the organizations you've mentioned and I see that there does seem to be a clearer consensus that supporting services are most simply understood as processes such as photosynthesis and soil formation that support the other three categories of services. This seems more consistent with how the services are presented on the AP Classroom daily videos as well, so I'll make an update to my slides and see if I can add a note into the video to clarify.
Thanks so much for this. You deserve way more subs this is super helpful especially bc I have a quiz next period lol. :)

Where do you get your cool slide backgrounds?

How do ecosystems lower health care costs?
filter pollutants = less people get sick = less resources spent on healthcare

Please take the time and put Spanish closed captioning. You are missing out, and we are too.
Hello can you please explain what think like a mountain means? We hear it in all the videos :) thanks!! 🏔️
For sure! I explain it in this video: ruclips.net/video/-WOVOic0ZWc/видео.html
