Video transcript

Hello everyone. And in today's video we have to follow a problem. We need to identify the largest terrestrial biomass that is extending across north America and Eurasia. And so we're giving certain bionics. But let me just help you recall where each of these bios are found so we can solve this problem. And this table is going to help us do just that. So grassland biomass are found in central north America, South America and Australia. They're not going to be the largest racial biomom found across north America and Eurasia. So we're going to cancel it out and remember that some of these bios may overlap. They may have areas that extend across the same continents. However, looking for the largest one extending across both continents. So let's keep looking. Then we have desert. These desert by OEMs are especially predominantly in africa, but they're also found in areas like the West to the United States. So these are not going to be the largest racial biomom. Again found across north America and Eurasia. So we're going to cancel it out. Then we have a parole. This Sapporo is usually found in California Mexico, but also some areas of europe again, is not going to be the largest bio found in north America and Eurasia. So we're going to cancel it out and this all lives out with Tiger, which is exclusively found in north America and Eurasia. And the thing about tiger is that it's so big that it occupies 11.5% of the earth land mass. So it is a huge bio found exclusively in these two. Um this area. So we're going to highlight it as being the final answer to our question. Thank you very much for sticking around until the end of this video, and I hope to see you on the next one.
