Predators hunt herbivores, plant eating animals, such as caribou, lemmings, and hares.
Tundra Soil Layers This is a graphic of the layers in Tundra soil, showing permafrost. If Tundra received just a few less inches of precipitation it could be considered a "desert".
Summers are cool and never completely melt the soil, creating permafrost. Polar bears love to eat fresh, fatty meat. The most extreme, polar northern areas experience essentially no vegetation.
The tundra climate is a very dry and bitterly cold climate found chiefly in the Arctic regions or at high alpine locations. Mosquitoes, flies, moths, grasshoppers, arctic bumblebees, and other insects are at the bottom of the arctic food chain.
Winter temperatures can reach -30 to -50 degrees Fahrenheit. Flowers often face the sun this is a quality known as "heliotropic" to gain heat. These alpine animals subsist on insects and plants in warmer areas. You might find lemmings, caribou, and arctic hares in the tundra. The frozen soil prevents trees from growing and water from draining into the Earth. It is also quite big. Animals who live in the tundra have special adaptations to survive.
During the summer, much of the snow and ice melts and forms soggy marshes and bogs. What are the Temperatures like in Tundra Climate? Another major concern is that the melting of the permafrost is contributing to global warming.
