With the help of suitable diagram describe the logistic population growth curve.
Thebest model for population growth of an annual plant like Phlox drummondii is:a.geometric growth.b.exponential growth.c.logistic growth.d.geometric growth during years with high rainfall and exponential growthduring years with low rainfall.e.geometric growth during years with high rainfall and logistic growthduring years with low rainfall.
These data were collected over a 5-year period for a perennial compass plant. What is the rate of growth of the population if the carrying capacity is 1000 (using 202 for starting population size)? What is the fastest rate of growth possible for this population?

- Describe the growth at various parts of the S-shaped curve of logistic growth.arrow_forwardINTERPRET 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).

- Describe how each of the limiting factors in the simulation affected population growth and carrying capacity(migration, predation, food, disease, and pollution). Include a reason why you think the limiting factor affected the population growth in this way.arrow_forwardYou monitor the white-tailed deer population for the Wright State campus and woods and estimate 14 deer in the first year and 21 deer in the second year. (A) Assume the deer population is growing geometrically. Based on these data, what is geometric growth rate constant (A)? (B) Geometric growth patterns can also be modeled exponentially. If modeled exponentially, would you expect the exponential growth rate constant () to be greater than, less than, or equal to 0? Why? You monitor the deer population for many years. The population grows for a few more years, then seems to stabilize around 75 deer. (C) Given this information, what would be a more appropriate model for the deer population growth? Why? (D) What factors might be limiting the population growth? Would these factors be considered density-dependent or density- independent factors? Why? it is equal to zero.

The idea is to remove individuals while keeping the population at a constant growth rate and size, but to find the size where the harvest is maximized. The greater the growth rate, the more individuals you can remove and not change the population size. Where is the growth rate at its maximum? To find this look at your logistic model simulator. 1. Set up a hypothetical salmon population where the carrying capacity is 20,000 fish, the maximumr is 0.7. According the the maximum sustainable yield (MSY), at what population size should we maintain the salmon while fishing?arrow_forward
