Transcript of 2 Biomes

Tundra Arctic fox The arctic fox has a deep thick fur which is brown in summer and white in the winter. It has shorter legs and a more rounded body shape then a normal fox to conserve heat. Snowy Owl The snow owl has white feathers which work as a camouflage in the snow to prevent its prey from seeing it. With a wingspan from 49in-59in it is one of the largest species of owls in North America Caribou The caribou migrate to new food sources in the winter and the summer and their diet changes to eating a variety of different plants throughout the year. They also have thick fur coats which keep them warm in the winter. Plants Arctic Crocus The arctic crocus have fuzzy covering on their stems, leaves, and buds which protect them from the wind. Shrubs Shrubs flower quickly in the summer, they require minimal amounts of sunlight to grow. Labrador tea bush The Labrador tea bush keeps its old leaves rather than dropping them which allows the nutrients to be preserved and protects it from the cold, wind, and drying out. Animals During the winter, a tundra is very cold and dark with an average temperature of −28 °C and can get as low as
−50 °C. In the summer the average temperature gets as high as 12 °C but can drop down to 3 °C and even below freezing. There is 25cm-15cm of precipitation every year which makes a tundra very desert like. Landscape The tundra biome is very flat terrain with a frozen layer of soil called permafrost. Permafrost is a word for the permanently frozen soil which makes it impossible for trees to grow. In the summer a thin layer of the topsoil thaws and creates small pools and marshes. Desert (Hot) Animals Scorpions Scorpions bury themselves in times of heat and drought. They sleep until dark and are usually active at night when the temperature is lower. Plants Spiny cacti They have thick, fleshy stems which conserve water in the inner layers of the plant. The roots can extend meters underground in search of water to absorb. Camels Mulga tree A mulga tree has one long main root into the ground that can reach as long as 7 feet into the ground for water. The branches of the mulga tree reach upwards, and are positioned so that they can channel any rainfall in toward their roots. The leaves of the tree are long and thin, allowing rainwater to run down them to the branches instead of running off them to the ground as with large, flat leaves. Camels have two rows of long eyelashes and can make their nostrils to close to protect them from the blowing sand. They also have broad, flat and thick skin on their feet which helps prevent them from sinking in the sand and not get burned when the sand is hot. Rattlesnakes Rattlesnakes avoid hot daytime temperatures by hiding in the sand underground. They emerge at night and on cloudy or cooler days to do their hunting. Prickly pear cactus The prickly pear cactus, also known as opuntia, has small pear like fruits which can be eaten very carefully. The thorns keep them safe from many animal predators. The prickly pear cactus stores water in its softer, inner tissue, which animals will eat for the moisture. Hot deserts have very little precipitation throughout the year. The majority of the rain comes in short periods of time where it rains very hard. Minerals in the desert don't get washed away which causes the soil to become very salty. In hot deserts the average precipitation is 25cm of rain annually. Hot days average 38°C and cold nights average around 7°C. Landscape Hot desert landscapes are generally rocky and sandy. There are usually few or no trees, and mostly only small shrubs and cacti. Some parts of deserts have few to no life forms, some sand dunes go on for miles. END
