Accepted Answer

Hi everyone welcome back, Let's look at our next question. It says blank is the collection of all the ecosystems on earth. When we're talking about the entire earth and its ecosystems, what we want is biosphere. So choice See you think about the fact that the earth is a sphere. Imagine we talk about the ecosystems on the entire sphere. So let's just walk through the other problems answers though, to understand why they are not the correct ones. Choice A is community and a community is a collection or a group of populations of two or more species that live in the same area. So a population is a group of individuals of the same species, but a community is populations of different species living in the same area. So we're gonna talk about their interactions with each other as well as their ecosystem as well as their environment. So the community is not the right answer because we're looking for the entire Earth and choice B is ecosystem and ecosystem is a community of organisms and their environment. So there are many ecosystems on earth. So there are multiple ecosystems on the biosphere and that ecosystem is both the living organisms and the non living elements of their environment that you would study together, but not the entire earth. So not our answer. And finally, we've got by OEM and that might be a little confusing in terms of remembering what it is versus the biosphere, but a biodome is an area that is classified based on the species, a distinct formation of flora, fauna and a biotic factors that live in that location, and the easiest way to explain it is if you kind of think of examples of bio, we'd say like a forest by OEM tundra biodome, a rainforest by OEM and these can occur in different areas. Um So you can have a rainforest by OEM uh in brazil, a rainforest bio on the island of Maui. So they're in different ecosystems, different areas, but they have similar flora, fauna and a biotic factors that characterize them, but it's still not the entire earth. So we're going to cross that out. And again, choice C biosphere is the collection of all the ecosystems on the earth. See you in the next video.
