A starting population has 150 animals. During the year, 50 animals are born and 30 die. Ten animals immigrate into the population, and 5 emigrate. Which represents the change in population size at the end of the year?       r = 1.8     ΔN = 20     ΔN = 50     ΔN = 25     r = 0.33

You study a population of mussels recently introduced to a section of the Rideau River 9 years ago. You know that 20 mussels were originally let go in the river by a resident. These mussels have no predators. You know from your research that, under ideal conditions, the instantaneous rate of increase of this mussel species is 0.17. You also think the conditions on the river were ideal when the mussels were introduced. After surveying the food available in the river, you estimated that there is enough food to support a population of 12,700 mussels. How many mussels do expect to be in the river now?

A population of rabbits, when introduced to a new environment with abundant resources, would most likely display what type of growth? Logistic growth Exponential growth Negative growth No growth
