Yesterday we learned about the connection between the biotic (living) and abiotic (not living) factors in the ecosystem of Yellowstone National Park. Wolves, deer, and trees are all biotic factors and connect together into a food web. Soil, rocks, and rivers are all abiotic factors that are influenced by the activity of the food web. Our work over the next two days is to research additional biotic and abiotic factors in the Yellowstone ecosystem, and to collect as much data as possible. We need numbers!
Browse through the sections of the Nature & Science page on the Yellowstone National Park website. Be warned – there is a ton of information! Your goal by the end of tomorrow is to come away with a deeper understanding of both the geology and the ecosystem of Yellowstone. Record as many facts as you can find about biotic and abiotic factors in your Google Doc.
Find specific population numbers for as many species of plants and animals as you can and record the data in your Google Doc. Cross-reference your list with the biotic factors you listed out yesterday. For example, there are an estimated 10,000-20,000 elk in the park. Be sure to read and take notes about the wildlife, plants, and life in extreme heat residing in Yellowstone.
