Journal Activities
Journal Activity #4 - Exponential Growth
1. If a population of rabbits experiences exponential growth, what might happen to the population of coyote in that area?
2.If the exponential growth factor for these rabbits is to triple every month, what is the rabbit population after 1 year if the original population is four?
3. Explain positive, negative, and zero growth rate. Provide an example of each.
Journal Activity #5 - Species Interaction
1. Viruses are the cause of many infectious diseases, such as common colds, flu, and chickenpox. Viruses can be passed from one person to another in many different ways. Under what conditions do you think viral diseases will spread most rapidly between humans?
2. What can be done to slow the spread of these viruses?
3. On page 218, copy Figure 10 - Five Major Types of Species Interaction into your notebook.
Journal Activity #6 - Estimating Wildlife Population
