- For each of the following, indicate if it describes what is generally a density-dependent or density independent population growth regulator. A windstorm blows all of the blue jays nests [ Choose ] out of the trees, crushing all of the blue jay eggs The size of a mouse population increases as [ Choose ] the number of predatory hawks decreases An Australian forest fire kills all of the sloths [ Choose ] An exterminator tents a house to kill all of [ Choose ] the termitesWhich of the following species is most likely to display geometric population growth? O Humans O Bacteria O Aphids O Corn O Tropical fishIn logistic growth, large values of r (e.g., >3) can cause the population size to stay greater than K for multiple generations briefly exceed K but then stabilize at K thereafter never increase beyond the initial number fluctuate chaotically gradually approach K and then stabilize at K thereafter
- ASAPIn a forest in India, there are 800 axis deer and 500 barking deer. The forest can support a maximum of 1,200 barking deer. The competition coefficient of barking deer on the axis deer is 0.25, and the competition coefficient of the reverse pair is 0.5. The intrinsic growth rate of barking deer is 2.0. Based on the Lotka-Volterra model, the population growth rate for barking deer is 416.67 Now, let's see if the two species can coexist in this forest. You are provided with some additional information: the carrying capacity of axis deer is 4,000. Determine if the two species can coexist.The growth of fish populations is the greatest at population sizes, medium small large very large none of these answers
- Population size (M) K NX K The figure depicts which type of population growth? logistic normal geometric Time (t) exponentialDuring a one-year period, a population of rabbits has a birth rate of 0.8 and a death rate of 0.1. The rabbit population consists of 50 organisms (at the beginning of the year). Which of the following is true about the rabbit population during this one-1 year period? O The rabbit population would increased by 35 rabbits during this year. O The rabbit population would decrease by 35 rabbits during this year O There would be a total of 500 rabbits at the end of the year 500 rabbits were born during the year.What does the logistic growth equation describe? Multiple Choice A population that crashes after very rapid, nearly exponential growth. A population that is increasing in size, but never reaches its carrying capacity. A population that is declining in size and with further time may become extinct. A population that grows steadily the population is small and more as it approaches the carrying capacity.
- Based on the equation for logistic population growth, Logistic Growth O A. new Individuals are added most rapidly at low population sizes. This figure displays the equation for logistic population growth and visualizes population growth as a function of time (number of generations) as it approaches carrying capacity. N stands for population size, K stands for carying capacity, and r stands for intrinsic rate of increase. O B. population growth never exceeds K. C. growth rate decreases as N approaches K. D. the population keeps growing when N equals K.
