The topic is about Yellowstone National Park. We learned about the food web and all the animals in that park. This one in particular is about the elks and the introduction of wolves. Something that I have learned in class is that there are many elks living in Yellowstone National Park, before when the wolves were taken away the population of the elks was raised. Later on the wolves came back. "More than 30,000 elk from 7-8 different herds summer in Yellowstone and approximately 15,000 to 22,000 winter are in the park". In the article one of the topic is Other Influences on Yellowstone's Elk Populations, it says, "Computer modeling of population dynamics on the northern winter range predicts that 75 wolves would kill 1,000 elk per winter, but that elk would be able to maintain their populations under this level of predation, and with only a slight decrease in hunter harvest." I say this statement is true, because wolves eat elks and since there is more population of elks, the wolves main food would be elks, I also think that elks would be able to maintain there population because it all matters on their food and the hunting people do. The food web is the main reason for all the animals there. Every animal counts on the food web, so its a good thing the wolves came back even though they aren't safe, they make the food web complete. In the article is says that the wolves eat the moose, bison, deer, and even one pronghorn antelope in the national park. Therefore, in class we learned about the food web and Yellowstone National Park and how the wolves were back in Yellowstone and how the population of elks was raised. We have learned a lot about Yellowstone and the animal life there, there are many facts and some are listed above.
