5

Multiple Select

Which is not a factor that determines a populations future?

1

Population Size

2

Population Density

3

Dispersion

4

Population Model

6

A population model is how scientists predict what might happen to a population

It is a hypothetical population

7

Multiple Choice

Question image

This is an example _________ dispersion

1

clumped

2

ramdom

3

Multiple Choice

Question image

What time of growth curve is this?

1

exponential

2

logistic

10

Exponential Growth

The per captia growth rate doesn't change even if the population gets very large (pg 322)

Slide image

11

Multiple Choice

Question image

What type of growth curve is this?

1

exponential

2

logistic

12

Logistic Growth

  • per capita growth rate gets smaller as the population approaches its maximum size (page 323)

Slide image

13

Multiple Select

Carrying Capacity (select multiple options)

1

is modeled on a logistic growth curve

2

is the population size that an environment can sustain

3

how much you can physically carry

14

Carrying Capacity

A population size may jump above or below the carrying capacity. This is very common to occur around the carrying capacity line rather than forming a perfectly straight line (pg 323)

15

Multiple Choice

Which is NOT an example of density dependent factors?

1

Competition within the population

2

fire

3

diseases and parasites

4

waste accumulation

5

predation

16

Fire!

Density-dependent factors tend to be biotic -living organism-related as opposed to physical features of the environment

Slide image

17

Multiple Choice

What is not an example of density-independent factors?

1

wildfire

2

flood

3

competition

4

severe weather

5

pollution

18

Competition

Density-independent factors can't keep a population at constant levels. These factors may lead to erratic, abrupt shifts in the population size (pg 324)

19

Multiple Choice

slowly growing population

long life span

few young

(pg 325)

Slide image

21

Multiple Choice

Which is not true about r-strategists?

1

small population

2

short life span

3

cockroaches

4

often described as exponential growth model

22
