As we can see from both the graphs we can observe that population size of one species is inversely proportional to growth rate of another species from this we can infer that as the population of species B is less the growth rate of species A is higher.
So to conclude this option A seems to be more appropriate answer.

The graphs show how yield Nild changes with population size N in two populations. Based on the relationships, you would conclude 10000 5000 10000 20000 30000 500 1000 1500 2000 A. The population on the left shows density independent growth and the per capita growth rater is a constant B. The population on the left shows density dependent growth and the per capita growth rater is a variable C. The population on the right shows density independent growth and the...

3. The graph below has axes to show the population sizes of a predator and its prey. The dashed lines are the predator and prey isoclines. Prey Population Starting at the circle, draw in what will happen to the two populations if they are following the pattern in the Lotka-Volterra model of predation. (Remember that BOTH predator and prey numbers are represented by a point on the graph.) Use a series of arrows to show what happens. 2. Imagine two...

A large population has a mean of 400, a standard deviation of 50, and is skewed right. For samples of size n=100 obtained from this population, the sampling distribution of the sample means has mean fe and standard deviation 0. Which of the following sets of graphs correctly display the population distribution and the sampling distribution of the sample means of size 100? Please note that the x-axis values differ within and across the options. A) Population Distribution Sampling Distribution...

For each of the intersections shown in the following figures, determine whether the data support each of the nine signal warrants. For each problem, and each warrant, indicate whether the warrant is (a) met (b) not met (c) not applicable (d) insufficient information given to assess. For each problem, indicate (a) whether a signal is warranted, (b) the type of signalization that should be considered, and (c) whether pedestrian signals and/or pushbuttons are recommended In all cases, assume that no...

a) You are studying a population of aphids with an initial
population size of 500. During a one-month period, you observe 40
births and 15 deaths in the population. Estimate the value of r for
that month, and predict the population size in three months (from
the initial population size). Remember that r is the per capita
rate of population increase. (Assume exponential population
growth).
