Tundra By Jacqueline Petsinis Abiotic Elements
The Food Chain in the Tundra Pictures of the Tundra Problems or limiting factors in the Tundra Where is the Tundra located ? Plants in the Tundra What animals are found in the Tundra? What is the Tundra The main animals found in the Tundra are : Polar bears, Caribou, Snowy owls, Arctic fox, Arctic hares and Musk ox. the melting of the permafrost can change the landscape and what species are able to live there
air pollution causes smog which can contaminate food sources
habitats in the Tundra can be at risk because of pipelines from people looking for oil and gas in the ground The Plants and Animals i just talked about were many of the biotic things in the Tundra. Some of the abiotic things are : The Tundra is a flat, treeless Arctic region found in Europe, Asia, and North America and parts of the soil are permanently frozen. The Tundras growing season is only 50-60 days a year. There are no trees because of the cold weather and frozen soil. Some plants still manage to grow. The plants that grow are : the Arctic Willow, Low shrubs, Sedges, Low lying grasses, Mosses such as Reindeer mosses, Arctic poppies, birches and dryads. Most plants will eventually die within the 50-60 days due to the cold. Introduction The biome I chose is the Tundra. Climate The Tundra is really cold and dry. It is cold for most of the year except a short summer which is about 6-10 weeks. During this 6-10 weeks the sun shines almost 24 hours a day . During the cold and windy months, the sun barley rises . The Tundra gets about 15-25cm of precipitation a year. In this world map the Tundra biome is in orange. The Tundra is the winter . The Tundra in
the summer. Temperatures in the Summer are from 3-12 degrees

Temperatures in the Winter are around -30 degrees More Plants in the Tundra Interesting facts about the Tundra the word 'Tundra' means tree less
the Tundra is the coldest biome
in the summer only the top soil layer will thaw
the Tundra covers one tenth of the Earths land area THE END Conclusion In conclusion, the Tundra is a
very unique biome because it is so cold, has no trees and very few plants can survive there. BY:
