Use the graphs to answer the question below. In each of the figures, the x-axis represents time, and the y-axis represents population size. The solid line is population size of Species 1; the dashed line is population size of Species 2. ir is ie ha А. В. С. D. The population represented by the solid line on Graph A above is growing... O Exponentially O Logistically

What is the population size after 20 timesteps assuming exponential dynamics, an initial population size of 5, and r=0.2? Round to nearest whole number. a. b. 273 С. 151 d. 1000 е. 303

Beetle populations is shown in the graph.  Explain why these interpretations are not as reliable as the data itself.

A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.

7) The following data has been obtained from the coastal haddock (Melanogrammus aeglefinus) fishery of Maine. The fishing season was divided into 10 periods. Period Catch per Period 1 208 2 195 3 168 4 132 5 91 6 80 7 63 8 56 9 48 10 33 It was also recorded that five fishing trawlers were in operation during each period of the fishing season. Question: What was the size of the haddock population originally available to the fishery?

A population is correctly defined as having which of the following characteristics? I. Inhabiting the same general area II. Belonging to the same species III. Possessing a constant and uniform density and dispersion III. Possessing a constant and uniform density and dispersion Only I Only I and II Only Il and III Only III I, II, and III

The population of individuals is growing at a continuous rate. The maximum growth rate is 0.35 and the carrying capacity of the population is 800 individuals. a. If the population size is 20 individuals, find the population growth rate. Show your work.  b.  If the population was nearing the carrying capacity, how would this rate compare to the calculated rate in part a? A  calculation is not required.

Regarding the population growth of Canada geese, which of the following statements is most likely true? O The population is increasing at a constant rate with time. O If modeled geometrically, A should be greater than 0, because the population is increasing. If modeled exponentially, r should be greater than 0, because the population is increasing. O None of the above statements is true.

Imagine a population of daisies that is growing exponentially. At the start of 1995, the population was 104 individuals. At the start of 2004, there were 1350 individuals. Assuming r remained constant, calculate r.
