100

 give an example of a r-selected species

Rats, spiders, (any animal that has a lot of offspring)

100

What is the maximum population a given area can sustain?

Carrying capacity

100

Give an example of a limiting factor

Disease, resources, habitat size. (anything that can limit the population size and stop growth)

100

What is the total fertility rate?

Average number of children born in a population.

100

What are the implications of a high infant mortality rate?

Public health, socioeconomics, and the society's well being

200

Give an example of  k-selected species

Elephant, kangaroo, (any animal that puts a lot of energy into parental care)

200

What is exponential growth?

Population growth with no limiting factors

200

How does increasing population impact food production and availability?

Food production rises and availability drops

200

What factors influence the total fertility rate?

Cultural norms, socioeconomic conditions, access to contraceptives, levels of education, and government policies.  

200

What is the role of medical technology in reducing mortality rates?

Improved medical treatment and early diagnosis help reduce mortality rates.

300

A species that can easily adapt to the environment and has many ecological niches is a..?

Generalist species

300

Population graph that repeatedly rises and falls below the carrying capacity 

Boom and bust cycle

300

How is population size affected by birth, death, and migration rates?

Birth and immigration increases population size. Death and emigration decreases population size.

300

How does TFR differ from the rate of natural increase?

TFR measures the average of children a woman will have in her lifetime and natural increase measures population growth rate from birth and death rates alone.

300

What does a triangular shape (wide base) indicate?

Population growth

400

A species that only can live in one environment and struggles to adapt is a..?

Specialist species

400

Death and birth rates of a post industrial stage

Low birth rates low death rates

400

How does carrying capacity impact population growth?

It sets a limit on how much a population can grow. This causes growth rates to slow down as it approaches the carrying capacity and can lead to a decline of a population. 

400

What is the net reproduction rate?

NRR is the average number of daughters a woman has in her lifetime

400

What are some potential reasons for high death rates in stage 1? (pre-industrial stage)

Poor medical care, poor sanitation, and high rates of infectious diseases.

500

What is the survivorship curve were lifespan has no effect on death rate

Survivorship curve II

500

Death and birth rates of a pre-industrial stage

High birth rates and high death rates

500

How do density-dependent and density-independent factors affect carrying capacity?

They limit population growth

500

What is the Replacement Fertility rate?

2.1 children per woman

500

What does I=PAT stand for?

Impact = population x affluence x technology
