2 Whats a Biome? Biome - Major types of ecosystems on land (not in the oceans) Similar biomes can exist in many places, but the animals that live there are different Biome - Major types of ecosystems on land (not in the oceans) Similar biomes can exist in many places, but the animals that live there are different

3 Biome Distribution

4 Tropical Forest

5

6 Temperature usually stays between 93ºF and 68ºF Rainfall is more than 100 inches per year Trees are very tall Produce 40% of the earths oxygen Temperature usually stays between 93ºF and 68ºF Rainfall is more than 100 inches per year Trees are very tall Produce 40% of the earths oxygen

7 Savanna

8

9 Type of grassland with shrubs and few trees Little rain falls Found on the edges of rainforests Warm temperatures year round but has a very dry season and a very wet season Lions, zebras, elephants, giraffes Type of grassland with shrubs and few trees Little rain falls Found on the edges of rainforests Warm temperatures year round but has a very dry season and a very wet season Lions, zebras, elephants, giraffes

11 Desert

12

13 Animals must be able to get underground in order to survive Some deserts are cold deserts Cover 1/5th of earths surface Rainfall (or snow in cold deserts) is around 15 cm per year Animals must be able to get underground in order to survive Some deserts are cold deserts Cover 1/5th of earths surface Rainfall (or snow in cold deserts) is around 15 cm per year

14 Chaparral

15

16 Found a little bit on most continents Hot and Dry Looks like the wild west Animals include coyotes, deer, horned toads, praying mantis Found a little bit on most continents Hot and Dry Looks like the wild west Animals include coyotes, deer, horned toads, praying mantis

18 Temperate Grassland

19

20 Large, rolling terrains Local climates determine what plants grow there Fires are common and stop large forests from growing Large, rolling terrains Local climates determine what plants grow there Fires are common and stop large forests from growing

21 Temperate Deciduous Forest

22

23 4 seasons - spring, summer, fall, winter Our area is a natural deciduous forest Animals adapt by hibernating in the winter Plants lean towards the sun Most land has been turned into farm land Soil is very fertile 4 seasons - spring, summer, fall, winter Our area is a natural deciduous forest Animals adapt by hibernating in the winter Plants lean towards the sun Most land has been turned into farm land Soil is very fertile

25 Coniferous Forest

26

27 Pine trees = Coniferous Forest Trees with needles Dont loose their needles in the winter Some animals hibernate in the winter, others fly south Many wildfires - trees have thick bark to protect themselves Pine trees = Coniferous Forest Trees with needles Dont loose their needles in the winter Some animals hibernate in the winter, others fly south Many wildfires - trees have thick bark to protect themselves

28 Tundra

29

30 Very cold Not many plants grow here If it starts to thaw out, its almost like a marsh Annual average temperature is -18ºF Animals include caribou, wolves, foxes, bears, deer Very cold Not many plants grow here If it starts to thaw out, its almost like a marsh Annual average temperature is -18ºF Animals include caribou, wolves, foxes, bears, deer

31 Break!! In the margin of your handout answer the following questions What kind of trees grow in a Coniferous Forest True or false: The tundra does not have many plants because it is so cold.
