Biome Tundra - Coggle Diagram
Biome Tundra
Tundra characteristics
Tundra has very little nutrients and food
Tundra is the coldest and harshest biome on Earth
Tundra's soil is rich in nitrogen and phosphorus
Simple plant structure
Low biodiversity
Plants are close to the ground
Short plants
Climate
150 to 250 millimeters of rain per year
-40°C to 18°C degrees
Humidity is relatively low in the tundra, and winds are high, adding to the dryness of the air.
Climate in tundra almost all year round dry, cold, and windy.
Animal life in tundras
Food web in the arctic tundra has the predators such as owls, foxes, wolves, and polar bears at the top of the chain. Predators hunt herbivores, plant eating animals, such as caribou, lemmings, and hares.
Polar Bear
As an apex predator in the tundra biome, the polar bear needs and eats lots of fat and flesh everyday. Polar bears mainly feed on seals. Polar bear are really reliant to floating ice is because that they need to feed on seals for seal's fat, they convert some parts of fat into energy while others into skin fat, skin fat gives them warmth while swimming in icy cold water.
Animals in tundra need a lot of energy to survive. Tundra animals need to has adapted to this harsh environment.
Animals in the tundra hibernates to minimize energy lost, they often sleep during the worst part of the winter and wakes up in spring. Animals before hibernation often hunts and eats huge amounts of food for their body to store enough energy and wake up at the right time in winter.
Location
Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, parts of Antarctica
60° and 75° of latitude
Soil in tundra
Gelisols or Cryosols soil type. This type of soil is the kind that lacks nutrients for plants to survive. Plants are an essential part of the food chain. But in tundras, plants have a very simple form, so only certain herbivores can eat them, therefore, certain carnivores will eat the herbivores. So in tundras, the animals and biodiversity is very low.
