Which of these is not an indirect value of species?
a. participate in biogeochemical cycles
b. participate in waste disposal
c. help provide fresh water
d. prevent soil erosion
e. All of these are indirect values.

Key Concepts

Ecosystem Services

Ecosystem services are the benefits that humans receive from natural ecosystems, including provisioning (such as food and water), regulating (such as waste decomposition and climate regulation), supporting (such as nutrient cycling), and cultural services. These services are critical to human well-being and environmental sustainability.

Indirect Value of Species

The indirect value of species refers to the roles that species play in maintaining and supporting ecosystem functions and processes that are not immediately apparent or directly utilized by humans. These functions include nutrient cycling, waste disposal, water purification, and soil stabilization, which all help maintain healthy ecosystems.

Biodiversity

Biodiversity is the variety of life forms in a given ecosystem or on the entire Earth, and it underpins ecosystem functioning and resilience. A rich biodiversity ensures that ecosystems are able to maintain their essential processes and continue to provide both direct and indirect ecosystem services.

Transcript

00:01 Okay, so we are here in chapter 6, and we're looking at for, we're sort of looking at what are the properties basically of these indirect value of species, right? so we're sort of trying to choose which one is not indirect.

00:19 And so when we go through here, the first choice is the biogeochemical cycles, right? and so what exactly is that? so that's sort of these cycles that happen naturally, where carbon, nitrogen, sort of things get absorbed or produced.

00:44 And you can't really put an economic value on that, right? the same way you can on selling fish.

00:51 So the biogeochemical cycles are definitely an example of an indirect value.

00:59 Okay, so we at least know that.

01:01 Let's move on.

01:02 So then it's waste disposal, waste disposal.

01:05 And so this sort of, what happens here is we're going to have, like, decomposition, basically, is what this is referring to.

01:18 So there's lots of organisms that aid in decomposition and help sort of influence and and speed this process.

01:37 And without it, things that might otherwise die, you know, think of animals that consume dead animals that they find, right? so without that consumption, that carcass is just going to lay on the earth and take much longer.

01:52 We don't really think about this.

01:54 You can't really put, again, a value, like a monetary value to it, but it has a huge value in society and in ecosystems.

02:08 And so that one also has some really impactful, but indirect value...
