Question is complete please explain why option B is correct why not D?
The basic metapopulation model explains how to find the proportion of occupied patches, ?, in a fragmented habitat. In this model, ? is 1 minus the probability of extinction, ?, divided by the probability of colonization, ?. ?=1−?/? The basic metapopulation model also allows for the calculation of extinction rates and colonization rates. Use the data in the table to calculate the missing rates of extinction and rates of colonization. Round your answer to three decimal places.

Plot survivorship curves for all three species illustrated in Table 1 on a single graph. Label the axes and provide a clear legend convert it and make use of legend, so for the first species it would be 6months=1unit, then for the second species 1yr=1unit, and the third species would be 50yrs=1unit
. Draw a species accumulation curve for the beetles in Area C3, based on the data shown in Table 2. Ensure that you calculate a standard deviation around each average number of species per sample; plot this on this figure. Make sure you label the axes and that you provide a legend. You will need to reassemble the samples in all possible combinations in order to derive the species area curve (provided)

INTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F. Gause, The Struggle for Existence (Williams and Wilkins, Baltimore, 1934). Figure 54-5 G.F. Gauses classic experiment on interspecific competition
