(a)
To describe: Each population get changes as time goes.
(a)
Answer to Problem 6E
The fox population starts at 160, decreases to 30, and then increases to 65
Explanation of Solution
Given information:
A phase trajectory is shown for populations of rabbits (R) and foxes (F).
Formula used:
The graph is plotted against x axis and y axis.
Calculation:
A phase trajectory is shown for populations of rabbits (R) and foxes (F):
It is need to describe that how each population changes with time.
The rabbits population starts at 600 approximately, decreases to 100, and increase to 1800 then decrease back to 950 approximately.
The fox population starts at 160, decreases to 30, and then increases to 65.
And the cycle starts again.
Conclusion:
The fox population starts at 160, decreases to 30, and then increases to 65
(b)
To sketch: The graph of F and R as the function of time.
(b)
Answer to Problem 6E
The value gets increases and decreases based on the table.
Explanation of Solution
Given information:
A phase trajectory is shown for populations of rabbits (R) and foxes (F). To make a rough sketch of the graphs of R and F as functions of time.
Formula used:
The graph is plotted against x axis and y axis.
Calculation:
A phase trajectory is shown for populations of rabbits (R) and foxes (F):
Consider the following table to sketch the graph of rabbits and fox population.
The following rough sketch shows the population of rabbits at different time periods.
The following rough sketch shows the population of foxes at different time periods.
Conclusion:
The value get increases and decreases based on the table.
