1. BIOMES

2. Terrestrial Biomes – large land ecosystems with characteristic plants and climate (temp./rainfall)
Plants are the foundation of ecosystems.
Energy enters an ecosystem through it’s plants and photosynthetic organisms (like algae, bacteria).

3. A biome’s climate is the limiting factor that
determines which plants can survive there.
The type of plants in a biome determine the type of animals which can survive there.
Energy flows from producers, to consumers,
to the decomposers.

4. Biotic Groups – Autotrophs and Heterotrophs
1. Bacteria Kingdoms Archaebacteria/Eubacteria –
2. Kingdom Protista – algae, protozoan, etc.
3. Kingdom Plantae – all plants
4. Kingdom Animalia – all animals
5. Kingdom Fungi – all mushrooms, mold, yeast, etc.

5. Tundra
Located near the poles
Permafrost – area just below the soil surface that stays permanently frozen

6. Tundra

7. Tundra
Rainfall – light
Summer temperature – 34oF
Mosses, lichens, grasses
Reindeer, foxes, artic wolves, lemmings

8. Taiga/Boreal Forest/Coniferous Forest

9. Taiga

10. Taiga/Coniferous forest
Found above 60o N latitude
Medium rainfall
Summer temperature - 54oF

11. Taiga
Trees produce cones – conifers
spruce, fir, pines (Christmas Trees)
They have cones and keep their needles all winter
Moose, black bears, lynx, wolverines

12. Temperate Deciduous Forest

13. Temperate Deciduous Forest

14. Temperate Deciduous Forest
20o – 60o N latitudes
Summer temperature – 75oF
Medium Rainfall

15. Temperate Deciduous Forest
Trees change colors in the fall and
lose their leaves in the winter.
Oaks, poplars, sweet gum, sycamores
Deer, rabbits, squirrels, raccoon, opossums

16. Grassland

17. Grassland

18. Grassland
Middle latitudes
Low rainfall
Average summer temperature – 70oF
Grass dominant plant

19. Grassland
Sunflower, goldenrods, clover
Bison, pronghorn antelopes, prairie dogs
The Midwest is considered the bread basket of America because of the large amount of wheat (a grass) grown there.

20. Desert

21. Desert

22. Desert
0o – 20o latitude
Very little rain
86oF

23. Desert
Cacti , sage-brush, mesquite
Kangaroo rat, snakes, lizards, birds, insects

24. Rainforest

25. Rainforest

26. Rainforest
Found near equators
A lot of rainfall/humid
77oF

27. Rainforest
Tall trees with dense canopies
Lots of biodiversity - plants and animals

28. Aquatic Ecosystems – Freshwater

29. Freshwater Ecosystems
Rivers, lakes, marshes, swamps
Lots of variation in plants and animals
from freshwater ecosystem to another

30. Aquatic Ecosystems - Marine - saltwater

31. Marine Ecosystems – 3 distinct areas
Intertidal zone – shoreline between low and high tide – available light and nutrients but
most stressed because of changing tides
2. Pelagic zone – m – light available – lots of organisms
3. Benthic – ocean floor – bacteria, worms, crabs

32. Aquatic Ecosystems – Estuary – freshwater
meets saltwater
