A student is writing a paper about animals that build their own homes. Which example should the student add to best develop this topic? Squirrels and owls find shelter in the hollow of trees, while foxes and skunks live in hollow logs. When hermit crabs need a new place to stay, they find an abandoned shell and move in. Thanks to gopher tortoises who tunnel, other species have a place to stay safe and warm. Beavers are nature’s engineers and construct lodges out of branches, rocks, and mud.
