Which of the following is NOT true regarding population density? As population densities increase, density dependent factors increase in influence on the population. The crude density, or number of organisms per unit area, is a good indicator of where those organisms will be found in the landscape. Population densities can be useful to wildlife managers trying to maintain game populations as a renewable resource. OPopulation densities can fluctuate overtime given their interactions among trophic levels.

Use the passage to answer the questions. Logistic Growth The carrying capacity of a population may be influenced by all except which This figure displays the equation for logistic population growth and of the following factors? visualizes population growth as a function of time (number of O A. availability of food generations) as it approaches carying capacity. N stands for population size, K stands for camrying capacity, and r stands for intrinsic rate of increase. O B. abiotic factors in the environment C. competition from other populations with similar resource requirements K= carrying capacity D. the population's intrinsic rate of increase (K-N) dN - rN dt K Number of generations rered MacBook Air 心.

Asian carp are an invasive species of fish. When the Asian carp invade a river or lake, they overtake the food and space from the native fish. What type of density-dependent factor would this be considered?          physiological change         predation         competition         disease and parasites

The carrying capacity refers to the Group of answer choices:  maximum sustainable population size for the prevailing environment. maximum growth rate of a population in which resources are unlimited. minimum amount of resources needed to sustain a finite population with zero population growth. minimum number of individuals in a population required to assure reproductive success.
