1. Land Biomes
Chapter 20

2. Biomes
Geographic area characterized by certain types of plant and animal communities
Contains smaller ecosystems
Rainfall and temperature are the major factors determining what biome is in a region
Not specific to a place
Ex. Desert biome doesn’t refer to one desert in particular but to any of them

3. Forests Needs enough rain and right temperature Three types
Not too hot, not too cold
Three types
Temperate Deciduous forest
Coniferous forest
Tropical Rain forest

4. Temperate Deciduous This is where you live
Deciduous = leaves that fall off
Producers include trees, grass, moss, ferns
Animals include bears, birds, rodents and even the platypus

7. Temperate Deciduous Rain 75-125 cm a year Temperature Summer 28 C
Winter 6 C

8. Coniferous Forest Don’t change much from winter to summer
Long cold winters
Coniferous = pine trees with cones

9. Coniferous Forest
Producers include pine trees mostly and some flowers, moss, wild potato
Animals include yak, llamas, goats, birds, snow leopards

11. Coniferous Forest Rain – 35-75 cm
Temperature 14 C in summer, -10 C in winter
Also called Boreal forest or Tiaga

12. Tropical Rain Forest More diversity than any other biome
Some animals only live in the tree tops (canopy) while others live on the ground.
Most nutrients are found in the vegetation

13. Tropical Rain Forest
Producers include bamboo, various trees such as coconut, lianas or vines, flowers and strangler fig
Animals include elephants, tigers, monkeys, bats and insects

15. Tropical Rain Forest Rain – up to 400 cm a year
Temperature -> 34 C during the day
20 C at night
Also called the jungle

16. Grasslands Also called steppes, pampas, prairies
Found between deserts and forests
Found on every continent
Most are flat with rolling hills

17. Temperate Grassland Prairie Rain 25-75 cm a year
Temperature – 30 C in summer
0 C in winter

18. Temperate Grassland
Producers include GRASS, and small flowering plants
Animals include prairie dogs, birds, mice, foxes, bobcats, coyotes, insects

20. Savanna Tropical Grassland 150 cm in rain a year Temperature –
Dry season 34 C
Wet season 16 C

21. Savanna Producers include GRASS with scattered trees
Animals include elephants, giraffes, zebras, gazelles, wildebeests, leopards, lions and hyenas

23. Savanna
Think of the Lion King

24. Desert
Hot, dry area
Plants and animals have adapted to gain and conserve water
Rain – less than 25 cm a year
Temperature- 38 C in the summer, 7 C in the winter

25. Desert
Producers include cactus, small flowering plants such as aster, and bushes
Animals include rodents, birds, bobcats, reptiles such as snakes, lizards, tortoise and gila monsters

27. Desert

28. Tundra Far North on tops of mountains Too cold for trees to grow
Permafrost – permanently frozen ground below the surface
Keeps water from draining keeping surface soggy and wet

29. Tundra
Producers include moss, grasses, berries, tea, small willow shrubs and lichens
Animals include caribou, musk oxen, lemmings, shrews, hares, birds, bears, fox and wolves

31. Tundra Rain – 30-50 cm a year Temperature 12 C in summer
-26 C in winter
