ToucanMonkeyTree frogSloth Animals live in habitats that match their bodies. Thick fur and blubber help in the Arctic, while climbing feet and bright colors help in the rainforest.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A polar bear has thick white fur to stay warm in the Arctic.
Fur traps heat close to the body so the bear stays warm in the icy Arctic.
2. A toucan uses its big beak to eat fruit in the rainforest.
The toucan's large beak helps it reach and grab fruits high in rainforest trees.
3. The Arctic is very cold and covered in ice and snow.
The Arctic stays below freezing most of the year, so water freezes into ice.
4. Monkeys use their long arms to swing through rainforest trees.
Long arms and strong hands help monkeys move quickly from branch to branch.
5. Seals swim in icy ocean water to catch fish.
Seals are excellent swimmers and hunt fish in the cold ocean water.

Polar bears overheat in warm places; their bodies are built for the cold Arctic.
2. Toucans live in warm, wet rainforests.
True False
Rainforests are warm and wet, perfect for the fruit trees toucans eat from.
3. Walruses use their tusks to help pull themselves onto ice.
True False
Walruses dig their tusks into the ice to help lift their heavy bodies out of the water.
4. Tree frogs could survive easily on an Arctic ice floe.
True False
Tree frogs need warm, moist air; they would freeze quickly in the Arctic.
