Why do certain organisms live in certain places?

2. Climate Climate vs. Weather Weather- right now
Climate- average weather

3. Climate 5 main factors Temperature changes and precipitation
Hot or cold?
Rain or hail or sleet or snow or freezing rain?

4. Climate 5 main factors Seasons
Bring changes in temperature and precipitation
Caused by Earth’s tilt

5. Climate 5 main factors Latitude
Closer to equator- warmer, not much difference in seasons
Farther from equator- colder, not much difference in seasons
Middle (temperate zone)- warm and cool, big different in seasons

6. Climate
5 main factors
Elevation
High elevation- colder than normal

7. Climate 5 main factors Bodies of Water
Warm ocean currents  warmer area
Bodies of water change temperature slowly

10. Biomes Looking at climate zones PLUS biotic factors  Biomes! 8 Biomes
Tundra
Deciduous Forest
Desert
Savanna
Coniferous Forest
Grasslands
Chaparral
Tropical Rainforest

11. Biomes- Tundra Climate Zone: Polar Temperature: Low (Cooooooold)
Permafrost (frozen land) year round
Little vegetation except moss, lichen, wildflowers
Temperature: Low (Cooooooold)
Long winters with very short summers
Precipitation: Low
Few inches to several feet of snow
Examples of Life: Caribou, grizzly bears, polar bears

12. Biomes- Coniferous Forest
Climate Zone: Temperate Continental
Full of conifers (pine tree type trees)
Smells REALLY good
Doesn’t let grass or other plants besides trees grow
Temperature: Moderate to low
Only 2 seasons each year
Precipitation: Moderate to low
Good amount of rain/ snow
Examples of Life: Elk, wolverines, moose, woodpeckers, rabbits

13. Biomes- Deciduous Forest
Climate Zone: Temperate Continental (or Marine)
Full of wide variety of trees
Oak, birch, ash, and maple
Temperature: Moderate
Only 4 seasons each year
Precipitation: Moderate
Good amount of rain/ snow
Examples of Life: Elk, wolverines, moose, woodpeckers, rabbits, raccoons, owls, etc

14. Biomes- Chaparral Climate Zone: Dry
Plants are typically tough with waxy outside
Keeps in water and stops from being eaten
Temperature: Moderate to High
Cool, wet winters with warm, dry summers
Precipitation: Low
Droughts and fires are common
Examples of Life: Deer and antelope

15. Biomes- Savanna Climate Zone: Temperate Continental
Lots of grass with trees far apart
Not much grows because of seasonal rain
Temperature: Moderate to High
High enough that not much grows and seasons are due to rain not temperature
Precipitation: Moderate but seasonal
Rainy season: cm of rain
Dry season: fires, parched animals
Examples of Life: Lions, giraffes, wildebeests

16. Biomes- Grasslands Climate Zone: Temperate Continental
Sooooo much grass, but very little trees
Not enough rain for trees
Temperature: Moderate
4 Seasons
Precipitation: Moderate
Enough rain for animals and grass (25-75 cm), not enough for trees
Examples of Life: Wild horses, birds, gazelles, other herbivores

17. Biomes- Tropical Rainforest
Climate Zone: Tropical Climate
SO MANY PLANTS!!
3 layers of plants- emergent then canopy and understory is beneath
Temperature: High
Only 1 season due to year-round warm, humid air
Precipitation: High
Over 250 cm per year
Examples of Life: poison dart frogs, birdwing butterflies, pythons, sloths, lemurs, geckos

18. Biomes- Desert Climate Zone: Dry Cactuses and succulents
made to not let water evaporate
Temperature: High
Change dramatically from daytime (SUPER HOT) to night (very chilly)
Precipitation: Low
25 cm of rain
Examples of Life: Rattlesnakes, kangaroo rats, reptiles, insects, spiders (more active at night)
