Which of the following about colonization and extinction is true? Extinction rat

Question

Which of the following about colonization and extinction is true? Extinction rates are higher for populations inhabiting larger habitats. Colonization rates are higher for patches that are less isolated. As the proportion of occupied patches increases, both colonization and extinction rates increase. Colonization rates are highest when the proportion of occupied patches is the lowest. Which of the following is not true? Population growth is driven by births, deaths, and dispersal. None are true. Density-dependent growth occurs when population density and individual growth are inversely related. Exponential growth rate doesn't account for change in birth and death rates over time. Type III survivorship is described as having high mortality rates later in life. Carrying capacity (K) is reached when birthrates and death rates are the same. Which of the following about source populations is false? They can increase the population size of sink populations to make them large. Are located close to sink populations, allowing for individuals from the sink population to emigrate to it. They support a positive growth rate of metapopulations. Are characterized by high emigration rates to sink habitats. They are characterized by high quality habitat.
