| 32. | Why do the walruses need the ice floes to survive? |
| They need the ice floes to float around the Arctic Ocean on. |  |
| The ice floes are the walrus's natural environment. |  |
| The ice floes give them protection from the ocean waters. |  |
| They rest on the ice floes after hunting for food and to stay away from polar bears. |
|
| | 33. | Why are the animals of the Arctic having trouble surviving? |
| Their prey have all gone inland or out to sea. |  |

| Their prey is all extinct, and there is nothing for them to eat. |

| She wanted to get her dinner. |
