WebMar 24, 2015 · We can find the doubling time for a population undergoing exponential growth by using the Rule of 70. To do this, we divide 70 by the growth rate (r). Note: growth rate (r) must be entered as a percentage and not a decimal fraction. For example 5% must be entered as 5 instead of 0.05. dt = 70/r WebIn this scenario, competition for food is a density-dependent limiting factor. In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases. lvh with repolarization abnormality
