Tundra vs. Rainforest

1. Tundra vs. Rainforest By Cailey Roberson and Mable Venable

2. Biotic Factors of the Tundra • Polar bears • Caribou • Harlequin ducks • Arctic fox • Arctic hares • Snowy owls • Musk ox • Rock ptarmigan • Grizzly bears • Lemmings • Wildflowers • Golden eagles • Mountain goats • Shrubs • Cushion plants • Sheep • Marmots • Birds • Insects • Bearberry

3. Abiotic Factors of the Tundra • Rocks • Temperature • Rain • Wind • Dirt • Minerals • Clouds • Water • Ice • Snow

4. Biotic Factors of the Rainforest • Orangutans • Gorillas • Sloths • Birdwing butterflies • Toucans • Tapirs • Jaguars • Capybaras • Spider monkeys • Macaws • Grasses • Buds • Leaves • Fruits • Mushrooms • Insects • Bats • Anacondas • Hark eagles • Oncillas

5. Abiotic Factors or the Rainforest • Water • Rain • Rocks • Dirt • Temperature • Fog • Clouds • Minerals • Wind

6. Limiting Factors of the Tundra • Poor soil • Limited growing season • Cold temperatures • Permafrost • Water • Food • Predators • pH level • Sunlight

7. Limiting Factors of the Rainforest • Getting sunlight • Water • Food • Predators • Land • pH level

8. Symbiotic Relationships Within the Tundra • The arctic fox and the caribou. • Sometimes, when a caribou is digging around for food, the arctic fox will let him and just watch. When the caribou is finished, the fox will go over to the caribou’s hole and dig deeper. • Tapeworms and lots of other animals. • Tapeworms can house in animals like caribou, moose, and wolves. • Caribou and shrubs. • Caribou eat shrubs, and when they use the restroom, the seeds are scattered.

9. Symbiotic Relationships Within the Rainforest • Leaf-cutter ants and fungus. • The ants protect the fungus and also feed it, while the ants store their larvae in the fungus. • Bromeliads and trees. • Bromeliads grow on top of tall trees. The tree isn’t damaged, but the bromeliad gets enough sunlight to survive. • Strangler figs and trees. • The strangler fig grows onto a tree, growing up and down it, then wrapping around its roots and soon killing the tree.

10. Arctic Foxes (Tundra) • Arctic foxes live in burrows. • Fur changes with the seasons. In the summer, its fur color changes to a brownish-gray to blend in with the rocks and few plants.

11. Harlequin Ducks (Tundra) • They prefer rough waters. • Pretty extreme ducks, in my opinion. • Nest on the ground. • Can easily climb up wet and slippery rocks. • Eat mollusks, marine worms, small fish and larvae attached to rocks underwater.

12. Snowy Owls (Tundra) • For camouflage, most of their feathers are white to blend in with the snow around them. • Feed primarily on lemmings and voles. • Nomadic birds. They go south for the winter.

13. Sloths (Rainforest) • Their slow movements direct attention away from them. • Algae grows on their fur, camouflaging them.

14. Oncillas (Rainforest) • Climb trees to hunt food sometimes. • They have long tails for balance. • Kind of small.

15. Toucans (Rainforest) • Toucans have sharp bills to crush berries and fruits. They also eat small birds and lizards. • Important to the rainforest because they scatter seeds. • Bright colors help to attract a mate.
