1. What is an estuary?

Extremely fertile area where a river meets an ocean; mixture of saltwater and freshwater; serves as a nursery for many species of fish

Slide3

2. What are examples of freshwater biomes?

Lakes, ponds, rivers, streams

Slide4

3. What biome is characterized by cold, dry conditions?

Tundra

Slide5

4. What are examples of a desert biome’s biotic factors?

Cacti. lizards, owls, desert rat, spiders, mesquite, white thorn

Slide6

5. What type of biome is a river?

Moving freshwater

Slide7

6. What is a wetland biome?

A land region that is wet or moist most all of the year

Slide8

7. What are biotic factors in a deciduous forest biome?

Bears, rabbits, variety of birds and insects, foxes, mice, deciduous trees, squirrels

Slide9

8. What land biome has the largest diversity of living organisms?

Tropical rain forest

Slide10

9. How is soil fertility in a deciduous forest dependent on the trees?

Fallen leaves decay and make the soil rich with organic matter

Slide11

10. Why are caribou and Arctic hares suited for the tundra climate?

The climate is cold and

dry – fur, extra layers of fat

Slide12

11. What is a marine biome?

A saltwater ecosystem – oceans, seas, coastal inlets and estuaries – Great Salt Lake, Dead Sea

Slide13

12. What is the benefit of estuaries to organisms in this aquatic biome?

Serves as a nursery for many species of fish

Slide14

13. How is a kangaroo rat able to survive in a desert biome?

A kangaroo rat is able to get all the water it needs through its food.

Slide15

14. What is the taiga biome?

The world’s largest biome located south of the tundra; has long cold winters, characterized by cone-bearing trees and dense forests

Slide16

15. What biome covers most of the land mass near the Earth’s equator?

Tropical rain forest

Slide17

16. What biome dominates the eastern portions of the United States?

Temperate deciduous forest

Slide18

17. What is meant by the climate of a biome?

Average weather conditions of an area over time; includes wind, precipitation, and temperature

Slide19

18. What is the intertidal zone?

Part of the shoreline that is underwater at high tide and exposed to the air at low tide

Slide20

19. What is the cold, treeless biome that covers about one fifth of the Earth’s land surface?

Tundra

Slide21

20. What are examples of abiotic factors in a desert biome?

Sand, rock, little water, sun, hot and sometimes cold temperatures at night

Slide22

21. What determines the types and number of species in a given area?

Precipitation and temperature

Slide23

22. What is the purpose of setting aside large areas of desert to be national parks?

To protect desert wildlife and prevent desertification

Slide24

23. What are the characteristics of a savanna biome?

Tall grasses, few trees, grazing animals, birds, predators of grazing animals, dry season, hot temperatures

Slide25

24. What are the characteristics of a biome with the shortest vegetation (height of plants)?

Cold and dry; permafrost, treeless area

Slide26

25. What are examples of biotic and abiotic factors of the taiga biome?

Spruces, elks, snowshoe hares, mosses, severe winters, dense forests, cold winters, mild summers

Slide27

26. What biome is typically found in harbors, lagoons, and inlets?

Estuaries

Slide28

27. What are the characteristics of a temperate rainforest biome?

Above average rainfall; cool temperatures, forests dominated by trees with needle-like leaves

Slide29

28. What are biotic factors of a coral reef?

Diverse ecosystem formed form the calcium carbonate shells, secreted by corals; algae, tropical fish, sharks, sponges, echinoderms, mollusks, jellyfish, bacteria,

protists

Slide30

29. What are examples of biotic and abiotic factors of grassland biomes?

Grass, few trees, grazing animals, small amount of rainfall, sun, rivers, lakes, predators of the grazing animals, birds, insects, dry season

Slide31

30. What are examples of standing freshwater biomes?

Lakes, ponds

Slide32

31. What is the difference between a tundra biome and a desert biome?

Tundra is cold and dry; desert is hot in daytime and dry; it can be cold at night

Slide33

32. What is precipitation?

Condensation of water vapor in the form of rain, snow, sleet, hail or freezing rain

Slide34

33. What are examples of biotic factors of a tropical rainforest?

Vines, primates, tall trees, orchids, sloths, and birds

Slide35

34. What are examples of terrestrial biomes?

Taiga, tundra, tropical rain forest, deciduous forest, temperate rain forest, grassland, desert

Slide36

35. What is the difference between a deciduous forest biome and the taiga biome?

Dominated by climax communities of deciduous trees which lose their leaves in the fall – Eastern United States; a cold forest region dominated by cone-bearing evergreen trees – largest biome lies just below the tundra biome
