Final answer:
Both populations of deer mice and wood rats are growing at the same rate of 20 individuals per year.
Step-by-step explanation:
In this scenario, the population of deer mice consists of 200 individuals with an r (population growth rate) of 0.1, and the population of wood rats consists of 100 individuals with an r of 0.2. To determine which population is growing faster in terms of individuals per year, we need to calculate the population growth for each population.
Population growth can be calculated using the formula:
Population Growth = r * N
Where r is the population growth rate and N is the initial population.
For the deer mice population:
Population Growth = 0.1 * 200 = 20 individuals per year
For the wood rats population:
Population Growth = 0.2 * 100 = 20 individuals per year
Both populations are growing at the same rate of 20 individuals per year.
