need help Define population.

Question 1 options:

A group of all living things in a given area


A group of organisms that are the same species interacting with each other in a given area.


All of the living and non-living organisms in a given area


Areas with similar climate and flora and fauna

Question 2 (2 points)
What does the x-axis represent?

Question 2 options:

Time


Starting population of Fog Beetles


The number of organisms in the population


exponential growth

Question 3 (2 points)
What does the y-axis represent?

Question 3 options:

Time


Starting population of Fog Beetles


The number of organisms in the population


exponential growth

Question 4 (2 points)
Move the growth rate r slider to its lowest value of 0.1, then gradually increase it. What happens to the population size as you increase the growth rate (the r slider)?



Question 4 options:

As the growth rate increases, the population size moves up and down rapidly.


As the growth rate increases, the population size stays the same.


As the growth rate increases, the population size decreases more rapidly. The slope flattens out.


As the growth rate increases, the population size increases more rapidly. The slope becomes steeper.

Question 5 (2 points)
Set the growth rate at r = 0.5, and make N0 = 500 individuals. What is N when t = 8? To answer this question, you will have to rescale the graph so that you can see the higher values of N: Click on the gear icon and change the Max value of Pop. (N0) to 30,000.

Question 5 options:

12,182


30,000


27,299


500

Question 6 (2 points)
The initial values for the fog beetle population are as follows:

Initial # of fog beetles (N0) = 2,000,

birth rate=.88 (b)

death rate= .05 (d)



What is the calculated population growth rate (r) for the beetles?

Growth Rate(r) = birth rate (b)- death rate (d)

Question 6 options:

.88


.05


.83


.94

Question 7 (2 points)
After 5 years, what would be the total population of fog beetles?

**write the number in the following format xxx,xxx** Don't include a label

Question 7 options:
Question 8 (2 points)
The growth rate you entered into the model predicts that the population growth of fog beetles will start to slow down and decline as time continues.

Question 8 options:
True
False
Question 9 (2 points)
What are two possible limiting factors that might cause the population of fog beetles to level off?

Question 9 options:

Disease and predators


habitat loss and more beetles immigrating to the desert


Natural disasters and more beetles immigrating to the desert


None of the above

Question 10 (2 points)
If a parasite began attacking the fog beetles increasing their death rate to .12, how would this change alter the growth rate of the fog beetles (remember r=b-d, use the information from the initial question about fog beetles)?

Question 10 options:

An increase in death rate would cause the growth rate to decrease to .76


An increase in death rate would cause the growth rate to increase to .98


An increase in death rate would not cause a change to the growth rate

Question 11 (2 points)
How would this new growth rate influence the population size at time t = 10?

(The old growth rate was .83 )

Question 11 options:

The new growth rate would result in a decrease of 2 million fog beetles over the course of 10 years.


The new growth rate would result in an increase of 4 thousand fog beetles over the course of 10 years.


The new growth rate would result in a decrease of about 4 million fog beetles over the course of 10 years.


There would be no change to the population after 10 years.

Question 12 (2 points)
The kudu population will reach its carrying capacity right around the 35 year mark (You may need to change the max value of t and adjust the max value of k to optimize the graph display).

Question 12 options:
True
False
Question 13 (2 points)
Assume a new plot of land is added to the park, increasing the carrying capacity to 350 kudu. How will the population size change?

Question 13 options:

The population would continue to grow at the same rate until it hit 200 and then it would grow at a slower rate until it reached 350 kudu


The population would continue to grow until it hit the new carrying capacity.


It would provide more space for the trophy hunters to move in and hunt the kudu.

Question 14 (2 points)
Reset the carrying capacity back to 200. Trophy hunters move into the area, leading to an increased death rate, which decreases the growth rate r to 0.15. How would this impact the population size? (Hint: Look at when the population reaches its carrying capacity, look at the T value)

Question 14 options:

The kudu would grow at a very slow rate for 30 years and then the growth rate would slow down.


It would take about 25 more years for the kudu to reach their carrying capacity.


The population would reach its peak in the first 10 years
