Limiting Factors of the Rainforest

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.

Symbiotic Relationships Within the Tundra

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.

Symbiotic Relationships Within the Rainforest

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.

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.

Harlequin Ducks (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.

Snowy Owls (Tundra)

Their slow movements direct attention away from them.

Algae grows on their fur, camouflaging them.

Sloths (Rainforest)

Climb trees to hunt food sometimes.They have long tails for balance.Kind of small.

Oncillas (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.
