The discrete logistic function (the one you can solve with your calculator) has a time lag built in = one generation. What would a greater time lag do to the outcome? increase the chances of population exceeding K decrease the chances of population exceeding K slow down population growth by decreasing r increase population growth by increasing r it would have little/no effect under all circumstances

If a population has a constant r = 0.3 Group of answer choices the per capita rate of population increase continues to accelerate as the population grows the time necessary for population size to double gets shorter as time goes by since population size is increasing exponentially the absolute increase (change in population size per unit time) is also constant the time necessary for population size to double is also constant
In the logistic model of population growth what are N and K and what happens if N>K and explain why. Ho w is the population growth affected if N=K?
When the of in = do + aN how do we the effects of "a" in this model? Choose at least one correct answer the negative effects of density on per capita birth rates B the density dependent per capita death rate the density independent per capita death rate the density independent growth rate the negative effects of density on per capita death rates E. Dinerent species feed on the nectar from flowers. One interesting example is the case in which bees and moths use the same food resources, but bees gather nectar by day while moths gather nectar by night. This pattern is a good example of: 125 Choose at least one correct answer A commensalism B. niche partitioning C competitive exclusion D intraspecific competition mutualism

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.

In 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
