more common in unpredicable environments
The maximum population of a particular species that an ecosystem can support indefinitely.
limiting resource
carrying capacity
population growth
density dependent factor
The carrying capacity of a population is determined by the
distribution of a population
amount of limited resources
number of offspring produced
fertility rates
What type of growth is shown in the picture?
Logistic
Limited
Reproductive potential
Exponential
Which of the following is an example of exponential growth?

change in population size over time
how old an organism has to be to reproduce
The maximum number of offpring an organism can produce is the ____________.
carrying capacity
growth rate
reproductive potential
density
What has the largest impact on reproductive potential?
having a larger number of offspring at a time
living longer

Which of the following linking women to population growth is not true?
Educated women find they need to bear less children to survive
Educated women are aware of family planning techniques
Educated women contribute less to their family income
Educated women spend less energy on raising children
What will reduce population growth?
decreasing literacy and women having more children
starving some people and taking away necessities of life
more people in cities with large families
increasing literacy, education, and access to healthcare as well as economic stability
What is this model called?
survivorship model
demographic transition model
industrialization model
growth rate model
In the first stage of the demographic transition
birth rates stay high but death rates start decreasing increasing population size
birth rates and death rates are both low so population starts decreasing
birth rates and death rates are high meaning high stable population
birth rates and death rates are decreasing so population growth starts slowing down
In the second stage of the demographic transition
birth rates stay high but death rates start decreasing increasing population size
birth rates and death rates are both low so population starts decreasing
birth rates and death rates are high meaning high stable population
birth rates and death rates are decreasing so population growth starts slowing down
In the third stage of the demographic transition
birth rates stay high but death rates start decreasing increasing population size
birth rates and death rates are both low so population starts decreasing
birth rates and death rates are high meaning high stable population
birth rates and death rates are decreasing so population growth starts slowing down
In the fourth stage of the demographic transition
birth rates stay high but death rates start decreasing increasing population size
birth rates and death rates are both low so population starts decreasing
birth rates and death rates are high meaning high stable population
birth rates and death rates are decreasing so population growth starts slowing down
What does the demographic transition model not consider?
immigration
life expectancy
education of women
industrialization
Which of the following would not cause a population to decrease?
increase in emigration
increase in immigration
increase in birth rates
increase in life expectancy
What is biodiversity?
variety of life on earth
variety and number of species in a given area
number of species on earth
variety of species in the biosphere
Why is the loss of biodiversity a concern?
Species extinctions are decreasing.
We would increase our ability to find new plan species.
Food webs do worse with more diversity.
Humans rely on biodiversity for items such as food, medicine, aesthetics, and oxygen.

met in such a way that a human population can survive
indefinitely at a standard of living similar to the current
one is

Community is all the populations in a given area whereas a population is the members on one species in a given area
Community is a rainforest whereas a population is all the organisms.
Non living factors in the ecosystem are _____
