1 The Biomes of the World I can classify differences between Deciduous Forests, Coniferous Forests, and Tropical Rainforests. I can determine the animals, plants, climate, and vegetation states that are involved in each of these biomes.

2 Our first stop What in the World is a biome??? The word biome is used to describe any type of environment on Earth that has a characteristic climate and group of living organisms.

3

4 Close your eyes and imagine you’re walking into your back yard. What biome do you think you’re in?

5 Deciduous Forest The deciduous forest has temperate climates with four distinct seasons. o Spring o Summer o Fall o Winter The deciduous forest is the only biome where the leaves change and fall off their branches. If you’re driving through the country and see these trees, you know you’re in a Deciduous forest! Average yearly rainfall cm ( inches) Average temperatures Summer- 82F, Winter 43F.

6 What animals do you think live in the Deciduous forest? Mice Deer Owls Raccoons Squirrels What are some other animals that might live in this biome?

7 Plants (Vegetation) of the Deciduous Forest What are some plants that you grow in your back yard? Pear trees Cedar tree Berry bushes Oak trees Maple trees Apple trees Can you think of anything else?

8 Now we’re getting on a train and travelling to Canada! What biome do you think we’re in now??

9 The Coniferous Forest (Taiga) The coniferous forest is the largest land biome on Earth. The average temperature in summer is 14C (57F) and in the winter -10C(14F) Average yearly rainfall is 35-75cm (14 to 29.5 inches) The winters are long and cold with summers being very short. The main characteristic of this biome is evergreen trees also known as conifers. Pine trees are one type of conifer The soil can be very rocky and poor

10 Where do you think Coniferous Forest biomes can be found? Canada Siberia They are not found in the southern hemisphere.

11 Coniferous Forest animals Take a guess! Black bears Grizzly bears Owls Foxes Otters Snowshoe hares Notice how SOME animals can live in MULTIPLE biomes.

12 Be brave folks for now we are getting on a plane and travelling to …… Brazil!

13 What’s in Brazil you ask?

14 Climate and Rainfall The Tropical Rainforest is very hot and wet because its normal location is very close to the equator. Rainforests like this one are very dense with trees that can block the sunlight. Because these trees are so tall and thick, very little sunlight reaches the forest floor. Average rainfall per year is inches! The average temperatures in the daytime are 93F and during the night 68F and very humid.

15 Tropical Rainforest animals In the Tropical Rainforest there are 4 levels in which different types of animals live on each to survive.

16 Animals of the Rainforest Forest Floor Worms Insects Understory layer Snakes (boa constrictor) Jaguar Tapir (kind of like a wild boar)

17 Animals Continued Canopy Gibbons (type of monkey) Sloths Cuckoos Emergent layer toucans Scarlett macaws Blue morpho butterflies

18 Plants (Vegetation) in the Tropical Rainforest What are some plants we might find as we walk through the rainforest? Bengal bamboo Mangrove trees! Durian trees

19 Biomes of the World Day 2 I can define the difference between the tundra biomes of the world I can define what savanna biomes are and desert biomes are. I can recognize the different plants and animals that live in each biome as well as their climates.

20 Now get ready to travel to Africa What biome do you think we’re in?

21 So what’s the climate? The climate here is extremely dry with only 10 inches of rain PER YEAR. The average temperatures for summer 100F with winter temperatures at 45F. So how do animals survive with this heat? Huge ears help jack rabbits get rid of their body heat. Kangaroo rats never need to drink. They recycle water from the food that they eat. Deep-rooted plants can reach groundwater as deep as 30m. Cacti store water in their stems and roots The residents of the desert biome have special adaptations to survive in a dry climate.

22 Desert Animals

23 Animals continued Animals also have adaptations for living in the desert. Most desert animals are active only at night, when temperatures are cooler. Some animals, such as the spadefoot toad, bury themselves in the ground and are dormant during the dry season.

24 Plants and vegetation in the desert Cacti store water in their stems and roots Some flowering plants bloom, bear seeds, and die within a few weeks after a heavy rain. What are some adaptations of desert plants? Some plants have shallow, widespread roots that grow just under the surface. These roots let plants take up water during a storm. The leaves of desert plants also have a waxy coating that helps prevent water loss.

25 Now let’s travel to Australia What biome do you think we’re in?

26 Climate in the Savanna Average yearly rainfall 59 inches Average temperatures in the dry seasons 86F! Wet seasons 68F! The savannas are found in Africa, India and South America. There is a little part of Northern Australia that is Savanna as well.

27 Animals of the Australian Savanna Zebras, giraffes, lions, and acacia trees are found in the savannas of Africa.

28 Plants and Vegetations of the Savannas Kangaroo Paw Jamaha tree Cycs

29 Our last stop is the Alaska! What biome do you think we’re in?

30 Arctic Tundra Climate Tundra biome have very low temperatures and very little precipitation (Rainfall). Winters in the tundra are long and extremely cold; summers are short, mild, and cool. Average yearly rainfall is inches Average temperatures in summer 54F and winter -15F. There are different types of tundra biomes. Polar tundra is the north and south poles and has layers of permafrost which is a layer of soil that stays frozen all the time. Alpine tundra is similar to arctic tundra and also has permafrost. It is found on top of a mountain where there are no trees because trees can’t survive in the cold.

31 Animals in Tundra Biomes. Can you guess what animals might live in this Tundra? o Arctic foxes o Reindeer o Caribou o Grizzly bears o Ermines (a kind of weasel) o These animals all have thick fur that protects them from the cold. o Some of these animals like the caribou migrate south for the winter.

32 Plants and Vegetation in the Tundra Because it is very cold in the tundra, most of the soil is frozen. Only the very thin top layer of soil is unfrozen and available for plants to grow. This limits the kinds of plants that can grow in the tundra to only small, low-growing types, such as o Mosses o Grasses o Small bushes Trees cannot grow in the tundra because their roots cannot grow deep enough into the soil.

33 Pop Quiz!! Choose the abiotic factors that characterize the tundra biome. o A. arctic foxes, wolves, snowy owls o B. warm, wet forests o C. very little rainfall, extreme temperatures o D. very low temperatures, very little rainfall Very low temperatures and very little precipitation are abiotic, or nonliving, factors that characterize the tundra biome.

34 Succulent plants store water. Given this characteristic, which biome would they be best suited to live? o A. freshwater o B. salt water o C. tundra o D. desert. Desert biomes have a very low rainfall. Organisms that store water, like succulent plants, are adapted to limited water conditions.

35 Please pass your graphic organizers to the front row. This is for a grade!
