Final answer:
The growth rate for a population of 1000 penguins, with 500 born and 200 dying each year, is 30% or 0.3.
Step-by-step explanation:
To calculate the growth rate for a population of penguins, we use the number of births and deaths per year to find the net increase or decrease in population. We start with a population of 1000 penguins, with 500 being born and 200 dying each year. The net increase is the difference between births and deaths, which is 300 penguins (500 births - 200 deaths).
To find the growth rate, we then divide the net increase by the initial population and convert it into a percentage:
- Net increase = Births - Deaths = 500 - 200 = 300
- Growth rate = (Net increase / Initial population) x 100 = (300 / 1000) x 100
- Calculating this gives us a growth rate of 30% or 0.3 when expressed as a decimal.
