Carrying Capacity Video Watch this video and be prepared to answer a few questions on the topic of carrying capacity. Which of the following is NOT an example of a limiting factor? Food Deer Population Shelter Carrying Capacity Graph Label the region of the graph that represents exponential growth and the region that represents carrying capacity. carrying capacity exponential growth Sort the following as either density-independent or density dependent factors Density-Independent Drought Hurricane Earthquake Temperature Flood Density-Dependent Competition Disease Food Shelter Parasites Fill in the blank As the prey population increases, the predator population increases. As the predator population increases, the prey population then decreases. As the prey population decreases, then the predator population decreases. If a population of 80 foxes lives in an area of 8 square kilometers, what is the fox population density? 80 foxes per square kilometer 64 foxes per square kilometer 10 foxes per square kilometer 8 foxes per square kilometer What does a positive population growth rate mean? Fewer people are being added than lost. The population is increasing in size. The population has reached its carrying capacity. two of the above Match each definition with the correct term. carrying capacity largest population size that can be supported in an area without harming the environment population density average number of individuals in a population for a given area exponential growth pattern of population growth in which the rate of growth keeps increasing as the population gets larger population growth rate how quickly population size changes over time population distribution way in which individuals in a population are spread over their area logistic growth pattern of population growth in which the rate of growth slows as the population nears the carrying capacity Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include low food supply lack of space weather all the the above
