Answer:
Main idea for the section 'About the Park':
In the section "About The Park" the tone that the author has displayed is an informative tone. Using phrases like "3,000 square miles" and "2 million acres of park" the author is giving irrefutable details. In addition, the main idea that the author is trying to convey is that the Yellowstone national park has many interesting things. Such as rare plants, thermal species, and even things for us humans to do!
Main idea for the section 'Climate':
Similar to the first paragraph, the author is using an informative tone. to The main idea of this paragraph is that the change in climate is having a negative effect on the park. The author says "Many species depend on deep snow to breed, raise their young, and hunt successfully." Therefore further supports the idea that the change in climate is not good for the well-being of the animals that reside in the Yellowstone national park.
Main idea for the section 'Animal Survival':
Once again, we see the author using an informative tone in this paragraph. The main idea that the author is trying to convey is that the Yellowstone bison have had an interesting past, and the park's management has worked hard to bring back the bison. We can see this by the author's use of words such as "extinction" and "population bounce back."
