Imagine a population of ragweed that is growing with r= 0.24. At the start of 1991, the population was 93 individuals. If ‘r’ remains constant, how many ragweed will be present at the start of 2005?
Imagine a population of daisies that is growing exponentially. At the start of 1995, the population was 104 individuals. At the start of 2004, there were 1350 individuals. Assuming ‘r’ remains constant, calculate ‘r’.
