APES Unit 3

Question 1

Generalist habitat

Answer 1

Tend to be advantaged in habitats that are changing.

Question 2

Specialist Habitat

Answer 2

Tend to be advantaged in habitats that remain constant..

Question 3

K selected species

Answer 3

Those present in stable and predictable environments that produce fewer offspring, have longer gestation periods, and provide long-term care after birth.

Question 4

r selected species

Answer 4

Those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood.

Question 5

which selected species are more adversely affected by invasive species

Answer 5

k selected species

Question 6

which selected species are more likely invasive species

Answer 6

r selected species

Question 7

Survivorship curve definition

Answer 7

Shows the percentages of members of population surviving at different ages.

Question 8

which selected species are typically predators

Answer 8

k selected species

Question 9

which species are known as alien species

Answer 9

invasive species

Question 10

which selected species are late loss species

Answer 10

r selected species

Question 11

Carrying Capacity

Answer 11

Maximum population of a particular species that a given habitat can support over a given period

Question 12

Overshoot

Answer 12

When a population exceeds its carrying capacity carrying capacity

Question 13

What is one environmental impact of an overshoot

Answer 13

resource depletion

Question 14

What is a major ecological effect of population overshoot?

Answer 14

dieback of the population because the lack of resources available causes famine, disease, conflict

Question 15

Fecundity

Answer 15

The ability to produce an abundance of offspring or new growth; fertility.

Question 16

Fertility

Answer 16

Number of offspring produced by a single female.

Question 17

Total Fertility Rate TFR

Answer 17

number of children born to an average woman in a population during her lifetime. Not to be confused with replacement-level fertility rate.

Question 18

Factors that affect TFR

Answer 18

Age at which females have their first child.
Educational opportunities for females.
Access to family planning,
Government acts and policies.

Question 19

Infant Mortality Rate

Answer 19

Number of babies out of every thousand born each year who die before their first birthday.

Question 20

Birth rate

Answer 20

The total number of individuals born in a population in a given amount of time.

Question 21

Crude Birth Rate (CBR)

Answer 21

Annual number of live births per 1,000 people in the population of a geographic area at the midpoint of a given year.

Question 22

Death Rate

Answer 22

The total number of deaths in a population in a given amount of time.

Question 23

Crude Death Rate (CDR)

Answer 23

Annual number of deaths per 1,000 people in the population of a geographic area at the midpoint of a given year.

Question 24

Change in population =

Answer 24

{(Births + Immigrants) - (Deaths + Emmigrants)}

Question 25

Growth Rate =

Answer 25

(Crude Birth Rate – Crude Death Rate + Net Migration Rate)/10

Question 26

Factors Limiting Global Human Population

Answer 26

earths carrying capacity and malthusian theory

Question 27

what is malthusian theory

Answer 27

the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population die off.

Question 28

Density dependent - how density affects population

Answer 28

Clean water
Clean air
Food availability
Disease transmission
Territory size

Question 29

Density independent - how density affects population

Answer 29

Major storms
Fires
Heatwaves
Droughts

Question 30

of year until population doubles =

Answer 30

70/growth rate

Question 31

Developing Country- Predominantly Agricultural

Answer 31

High infant mortality rates
More children in the workforce
Less healthcare and food production
Typically faster growth rates
Lower income
Typically lower literacy rates

Question 32

Developed Country - Predominantly Industry

Answer 32

Low infant mortality rates
Less children in the workforce
Better healthcare and food production
Typically slower growth rates
Higher income
Typically higher literacy rates
