Back 1

1. Births

2. Deaths

3. Immigration

4. Emmigration

Front 2

Life history traits relate to reproduction and include:

Back 2

1. Time to reach reproductive age

2. Frequency of Reproduction

3. Number of offspring

4. The amount of parental care given to the offspring

Front 3

Limiting factors are environmental factors that may limit population growth. These include:

Back 3

available Food, available Water, available Space, accumulation of harmful Waste products, predation, pathogens, temperature, fire, flood, and storms.

Front 4

How do limiting factors restrict population growth?

Back 4

-decrease the birthrate -increase the deathrate -increase the rate of emigration

Front 5

Three ways populations may change over time are:

Back 5

(two are growth models)

1. Exponential growth –

(Growth model) 2. Logistical growth – (growth model)

3. Population - Cycles

Front 6

Which three factors largely determine climate?

Back 6

1. latitude

2. nearness to a large body of water

3. Mountains

Front 7

What is latitude and how is it measured?

Back 7

The middle line is the equator at 0 degrees. The top line is 90 degrees North, the bottom is 90 degrees South

Front 8

What is the equator?

Back 8

-The center measured latitude What do the tropic lines (tropic of cancer and tropic of Capricorn) indicate?

Front 9

What do the tropic lines (tropic of cancer and tropic of Capricorn) indicate?

Back 9

-The lines indicating the tropics (it is in between them,)

Front 10

Where are the tropics?

Back 10

-In between the tropic of Cancer and of Capricorn

Front 11

Why do tropical regions of the earth have the warmest climates?

Back 11

-Because they are the closest to the equator which means that they get the most sunlight

Front 12

Where are temperate regions of the earth?

Back 12

-In between the polar and tropic regions on both the top and the bottom of the equator.

Front 13

Where are polar regions of the earth?

Back 13

-Close to the poles (90 degrees North and South)

Front 14

What effect do mountains have on temperature?

Back 14

-The higher the altitude the cooler it is.

Front 15

What effects do mountains have on rainfall?

Back 15

-The rainshadow effect

Front 16

What is a biome?

Back 16

-a large naturally occurring community of flora and fauna occupying a major habitat

Front 17

2- savanna

Back 17

-Aren't forrested, grassland.

Front 18

3- desert

Back 18

-Tropical areas and temperate areas -Hot or cool temperatures, just characterized by little to no rainfall -Rodents, lizards, snakes, insects they mostly come out at night -annual plants that only grow when there is rainfall -Water can run off and create a flash flood when there is water because there are no plants.

Front 19

4- chaparral

Back 19

-Found all around the mediterranian Sea -Named for a particular kind of shrub -dense evergreen shrubs -mild winters -rainy winters, the summers are hot and dry -frequent fires -deer, birds, snakes live there

Front 20

5- temperate grassland

Back 20

-Praries -most of it in the Northern America has been converted to farmlands -Not tons of trees except around bodies of water -Hot summers, Cold winters, moderate rainfall -Frequent fires -bobcats, coyotes, snakes, burrowing animals, insects, large grazing mammals live there

Front 21

6- temperate deciduous forest

Back 21

-Trees that lose their leaves seasonally -Hot summers Cold winters, high rainfall -deer, squirrels, birds, mice, snakes, foxes -In the Eastern U.S. but a lot of it has been converted to farm land

Front 22

7- coniferous forest

Back 22

-Pine trees/borio forrest/taiga -moose, bears, migratory birds, wolves

Front 23

8- tundra -Has no trees

Back 23

-Low growing plants, shrubs grasses, mosses, lichens, annuals -migrant birds, caribou, wolverines, foxes, wolves -little to no precipitation -High winds

Front 24

Tropical forests are _____ in areas that receive abundant rainfall year round, and ______ in areas that are mainly dry or that have wet and dry seasons.

Back 24

tropical

Temperate

Front 25
