  • Population Growth In Paramecium

    exponential population growth represents the population increase under an ideal condition, resulting in a J-shaped growth curve plotted over time. It is different from the S-shape that the logistic population growth illustrates. On the contrary, with the limitations of food supply, predators and other environmental factors, the logistic population growth model modifies the changes of the growth rate as the population size reaches the carrying capacity, which is symbolized by K, meaning the maximum population size that a particular environment is able to maintain (Campbell and Reece 2011). The per capita rate of increase is the difference between the per capita birth rate, “the number of offspring produced per unit time by an average member of population”, and the per capita death rate, the number of deaths per individual per unit time (Campbell and Reece 2011). It implies the population will increase as the per capita rate of increase, r, is larger than zero, which in turn, shows that a negative r will lead to the decrease of the population. Unlike in the logistic population growth, the per capita rate of increase goes to zero while it is at the carrying capacity, the per capita rate of increase is maximized for the exponential population…

  • Effects Of Population Growth

    the earth has seen an astonishingly dramatic increase in the human population on earth. Humans have been on this planet for an estimated three million years and we have grown to a current population of approximately seven billion. Environmental scientists question the limits of the earth and how long many people it can accommodate before too much of a toll is taken and the population can no longer be sustained by the resources we have on earth. For thousands of years, the hunter and gatherer…

  • Logistical Population Growth Essay

    Paramecium population in the lab (graph a) appears to have a logistical population growth. Visually, the data and trend line of the graph create an S-shaped curve, which is the shape of a logistical population growth. A logistical population growth is a population growth that initially occurs at a constant rate of increase over time, but then levels out as the carrying capacity of the environment is approached. For 10 days the population increases at a steady rate. However, after day 10 the rate…

  • Pros And Cons Of Population Growth And Globalization

    Population growth and globalization are impossible to completely restrain. Exponential growth of the population has been happening for the last two-hundred years and growth will continue. In some societies, large families are almost required while in others the birth rate has declined. As technology increases globalization occurs at a faster rate. It is almost impossible to distinguish where in the world many businesses are based or where some products originate. Integration and growth are…
