Some bushes like blackberry bushes grow in dense groups. Which type of distribution pattern does this represent, and what is the advantage of this distribution?
A. This is a clumped distribution that enables more reproductive success due to proximity to other individuals.
B. This is a uniform distribution that allows more protection of offspring for the colony.
C. This is a random distribution that allows individuals to offer protection to each other from predators.
A. This is a clumped distribution that enables more reproductive success due to proximity to other individuals.
True or False:
A low population size and a random dispersion would result in the LEAST competition for resources?
TRUE.
Which change would cause an increase in the size of a population?
A. increase in emigration and decrease in births
B. increase in deaths and decrease in immigration
C. increase in immigration and a decrease in emigration
C. increase in immigration and a decrease in emigration
The ______________________ was the time period between 1946 & 1964. Nearly 80 Million people were born during this time. Lately there have been a lot of jokes at this generation including the meme "Ok Boomer"
Baby Boom
What are the THREE types of Population Distribution/Dispersion patterns?
Clumped, Uniform, Random.
The Population Change Equation is as follows:
(Births + Immigration) + (Deaths + Emigration)
False - It is actually:
(Births + Immigration) - (Deaths + Emigration)
If a large group of wolves in Yellowstone emigrate from Yellowstone to southern Canada how will this impact the remaining population in Yellowstone?
A. The Yellowstone Population will remain the same.B. The Yellowstone Population will increase.
C. The Yellowstone Population will decrease.
C. The Yellowstone Population will decrease.
True or False:
Genetically engineered crops can fight disease and insects. Not only is this a positive of GMOs, but another positive is they help decrease the amount of pesticides used.
True!
Sharks are known to prey on Rays. As the population of Rays decreases, few Sharks are available to reproduce. Which statement about carrying capacity is correct?
A. As the Shark population passes the ecosystem's carrying capacity the Rays population decreases.
B. As the Shark population passes the ecosystem's carrying capacity the Rays population increases.
C. The Shark population has no impact on the ecosystem's carrying capacity for the Rays population.
A. As the Shark population passes the ecosystem's carrying capacity the Rays population decreases.
True or False:
Since the carrying capacity of the environment tends to remain constant the size of a rat population will also tend to remain constant.
True
Wolves are predators, they prey upon deer. Deer are their primary source of food. If the deer population decreases due to over-hunting how will the impact the carrying capacity of the wolf?
A. The carrying capacity will be unaffected as Wolves have other food sources.
B. The carrying capacity will be increased now that there is room for more organisms.
C. The carrying capacity will be reduced significantly with the loss of a primary food source.
C. The carrying capacity will be reduced significantly with the loss of a primary food source.
Which of the following may result if more farmers begin to plant only genetically modified crops that have an increased tolerance to insects?
A. Natural selection will cause humans that eat these crops to become genetically immune .
B. There will be an increase in the toxicity levels in humans who eat these crops.
C. The genetic diversity of the crops will decrease, which may cause problems for humans in the future.
C. The genetic diversity of the crops will decrease, which may cause problems for humans in the future.
Which change would increase competition among a population of wolves in an ecosystem?
A. increase in birth rate
B. increase in death rate
C. increase in emigration
D. increase in carrying capacity
A. increase in birth rate
True or False:
When a population reaches carrying capacity on a population graph and stays with the carrying capacity, this means the populations birth rate is equal to its death rate.
TRUE
If a population of sharks has a higher birth rate than death rate in a single year, what will happen to the overall population size?
The Population will INCREASE in Size.
True or False:
Density-Independent Factors are factors that are affected/effected by the size of a population.
FALSE!
Density-Independent Factors are imapcts that have nothing to do with a populations size. They are impacts like hurricanes or earthquakes that may decrease a population.
Name ONE Thing that can increase the carrying capactiy of a population.
Any of the Following:
Increases of Food, Increase of Water, Increase of Space.True or False:
A Survivorship-Curve is best described as a horizontal graph seprated by males and females that helps predict future population growth.
FALSE:
That best describes Age Structure Diagrams!
There are 150 Oak Trees per square kilometer in a 10-square-kilometer area of Georgia. To which population characteristic does this information refer?
Population Density
True or False:
Examples of density dependent factors are, availability of Food & Water, or the incidence of Diseases.
True!
Density-Dependent means that it is an affect/effect caused by the size of a population. (example - too many predators means they will compete which may reduce the amount of prey available, lowering availability of food.)
