A team of 102 scientists spent a year surveying a small area of the San Lorenzo rain forest in Panama to count the number of species of arthropods living there. After collecting 129,494 specimens—using nets, traps, shovels, tree-climbing harnesses, helium balloons, and other creative gear—it took the team eight years to sort and identify the arthropods.A team of 102 scientists spent a year surveying a small area of the San Lorenzo rain forest in Panama to count the number of species of arthropods living there. After collecting 129,494 specimens—using nets, traps, shovels, tree-climbing harnesses, helium balloons, and other creative gear—it took the team eight years to sort and identify the arthropods. Use the data in the graph to analyze the following statements. Select True or False for each statement, then correct any false statements to make them true. T/F All taxa shown in the graph are insects. T/F All taxa shown in the graph have segmented bodies and limbs. T/F All taxa shown in the graph are terrestrial. T/F If the researchers had sampled for mollusks, they probably would have found almost as many species as they did for arthropods.

Welcome back. Let's look at the next problem here. It says the study of interactions of different populations with their environment is termed. And we recall that when we talk about the interaction of living things with their environment, that's in general ecology. When we look at our answer choices um We see that we have two choices that have the words ecology in them. We can rule out here. We have bio geography. Um bio geography is the study of the distribution of species and ecosystems in a geographic place over time. Um So it's not the interaction between living things in their environment. So that is not our answer here. And then choice D. Is sociology. Sociology is the study of human relationships and institutions. So not our answer here again, helped along by the fact they don't have the term ecology which is where we're studying the interaction of living things with their environments. So we've got our two choices left ought ecology and sin ecology. Well one helpful key can be that when you have to see the prefix auto it usually has to do with self and that prefects. Sin think of like synthesis you mean something involving um together. So we're talking about the interactions of different populations of their environment and that term is choice B. Sin ecology. So they are in interactions of different populations or you might think of interaction of a community um of of species with their environment. So looking at multiple different species populations together and how they interact with their environment. That's as opposed to ought ecology which would be the study of the one single individual species, uh interaction with its environment, sometimes called species ecology. So that's not our answer choice. Because we're looking for the interactions of different populations with their environment. And that's choice. B. Sin ecology. See you in the next video.
