4/17 or 4/18: Warm Up 4Habitat Change

A small, short-furred, gray animal called a divo lives on an island. This island is the only place on Earth where divos live. The island habitat is warm and provides the food the divos need, which is tree ants. The divos live high in the treetops, hidden from predators. One year the habitat experienced a drastic change that lasted for most of the year. It became very cold and even snowed. All of the ants died. The trees lost their leaves, but plenty of seeds and dried leaves were on the ground.

List any of the things you think happened to most of the divos living on the island after their habitat changed.

A. The divo's fur grew longer and thicker.

B. The divos switched to eating seeds.

C. The divos dug holes to live under leaves and beneath rocks.

D. The divos hibernated through the cold period until the habitat was warm again.

E. The divos died.

Explain your thinking. How did you decide what effect the change in habitat would have on most of the divos?
