Habitat Change

Habitat Change

How does a change in an organisms habitat impact them?

The Divo

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 plenty of the divos' only food -- tree ants. The divos live high in the treetops, hidden from predators.

The Divo (continued)

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.

Poll

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

• The divos' fur grew longer and thicker.

• The divos switched to eating seeds.

• The divos dug holes to live under the leaves or beneath rocks.

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

• The divos died.

Open Ended

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

Now for some real life examples...
