Practice Problems
1) In a population of 50 tigers, in one year 10 tigers are born and 20 tigers die. What is B, D, dN/dt, b, d, r?
2) Draw the graph that plots how the population size changes over time in exponential growth.
3) Define the carrying capacity.
4) Describe in words how the population size varies over time in logistic growth when the initial population size is much smaller than the carrying capacity.
5) The Gray Angelfish (shown at the top of the post) is one of my favorite species living on coral reefs in the Caribbean Sea. This species feeds on sponges and is prey for larger reef fishes such as baracudas. Why is the reef not covered with Gray Angelfish?
