Webmethod works at capturing the organisms in the photographs. See the Photoquadrat lesson for more details. Questioning Strategies: How could we figure out how large the population of a species is in an area? Counting, or making a list of species, but if there is a lot of something that may take a very long time. Web16 nov. 2024 · To do this, you start off with figuring out the ratio of 85:87 isotopes, which as the question told you is: 2.5:1 (because the 85 isotope is 2.5x greater in abundance than the 87 isotope). This then equals: 5:2 (I just prefer looking at it this way as there are no decimals, but you can work it out from the previous ratio just as easily).
