Flashcards in CHAP 8 Deck (38):
1

What is biome

Geographic region with relatively uniform geographic structure

2

What is the Köppen climate classification system

Most popular climate classification system primarily that uses temperature and precipitation

3

Where are tropical rainforests found?

Low latitude, low land tropics

4

What biome has the highest biodiversity

Tropical rain forest

5

Why do tropical rainforests have complex vertical structures

Trees are in competition for sunlight

6

What are epiphytes

Plants that grow on other plants but not parasitic

7

Where are tropical seasonal forest found

Low land tropics that have a winter drought

8

Why are some trees species in tropical seasonal forests deciduous

Because of drought

9

How long are the dry seasons in tropical seasonal forests

Weeks to a few months

10

Where are tropical savannas found?

Tropical regions (have wet summers dry winters)

11

What are the summers and winters like in tropical savannas

Wet summer dry winter

12

where are temperate grasslands found

Mid latitudes, continental interior moderatly dry areas

13

what are the annual temperature ranges of temperate grasslands like

Large annual temp range

14

What makes up most of the biomass in temperate grasslands

Grasses

15

Why does the height of grasslands in the North American interior decrease as you go farther west

It gets drier so the grasses are shorter

16

How intact is the temperate grassland biome in North America

Not very intact

17

Where can Mediterranean biomes be found

Southern California

18

When are the wet and dry seasons in Mediterranean biomes?

Wet winter dry summer

19

Why have some plants in Mediterranean biomes evolved sclerophyllous leaves

To prevent water loss and herbivory

20

Which of the following is not an adaptation of plant in fire disturbance areas

These are: Root, Sprouting, Thick bark, cerotinous, cone

21

Where are temperate deciduous forest biomes found?

Mid Latitudes large temp range and can have freezing Winters

22

Why do many trees in the deciduous forest biomes lose their leaves in winter

They're not going to be productive

23

What are primary forests

not significantly modified by people/ old growth forests

24

What are secondary forests

Regrown forests that have been disturbed by people or natural disaster

25

Where are temperate rainforest biomes found?

Mid Latitudes

26

What is the defining characteristics of temperate rainforest biomes

Dense canopy large trees

27

Where are boreal forests biomes found

Mid upper latitude, Continental interiors

28

What are coniferous trees

Cone bearing trees

29

Why are boreal forests dominated by coniferous trees

Cold tolerant needle leaves

30

Why are montane forest biomes so climatologically diverse

Can be found in any latitudes

31

Where are tundra biomes found

Anywhere where its told cold for trees to grow

32

How is an alpine tundra different from a northern tundra

Alpine is high elevation northern tundra is about latitude

33

What kind of soils are associated with tundra biomes

Perma frost soil, Permanently frozen frost

34

Where are desert biomes found

Chronic moisture deficits

35

What is the defining characteristics of desert biomes

Moisture deficits

36

How much of the earths land surface is covered with a desert biome

30 percent

37

At what latitude are hot deserts generally found

20 to 30 degrees north and south latitude

38

How long are the dry seasons in tropical savannas

7 months
