Summary Introduction
To determine:
The growth rate of population if
Concept introduction:
Logistic population growth refers to a growth rate pattern, in which growth starts to decrease as the population size (N) starts reaching the carrying capacity (K). Ecosystem’s carrying capacity refers to the maximum number of individuals that the ecosystem can sustain providing the food, water, habitat, and other necessities. It can be determined as the maximum load that ecosystem or an environment can sustain.

Draw a graph with a growth curve for a population that starts at 10 individuals and experiences exponential growth. Draw a second graph with a growth curve for a population that starts with 10 individuals and undergoes logistic growth. The second graph should have a carrying capacity of 100 individuals. Please give a proper written explanation for the graphs.
Write a generalized model for exponential population growth. Define your terms. Then,
draw a plot showing an example, being sure to label your axes.
Show how you build the logistic model for population growth from the exponential model equation? What part of the logistic growth equation produces the sigmoidal growth curve?

- When does the growth rate of a population following the logistic model equal zero?the logistic model is given as dN/dt = rN (1-N/K)arrow_forwardUse this graph of the idealized exponential and logistic growth curves to complete the following. a. Label the axes and curves on the graph.b. What does the dotted line represent? c. For each curve, indicate and explain where population growth is the most rapid. d. Which of these curves better represents global human population growth?arrow_forwardThe maximum sustainable yield (MSY) is the highest rate at which a potentially renewable resource can be used indefinitely without reducing its available supply. 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
- Distinguish between the exponential and logistic growth of a population and describe the nature of their growth curves. Define environmental resistance. What is the carrying capacity of an environment? Define and give an example of a population crash.arrow_forwardExplain the differences between equations for exponential population growth, logistic population growth, and Lotka-Volterra models for competition. Illustrate how and explain why these equations yield different trends?arrow_forwardThe per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates.
