Question 1 (2pts): You are a biologist studying two species of lizards. Lizard Alays eggs in large clutches of 20-50. These clutches are buried and the lizard does not return to tend them. When the young hatch, they suffer high rates of predation. The few that survive grow to adulthood. Lizard B lays only two eggs. It tends to a nest until the young hatch and carries them on its back until they grow large enough to fend for themselves. The survival rate for Lizard B's offspring is nearly 100%. A) What type of survivorship curve is demonstrated by Lizard A? Describe one advantage and one disadvantage of this reproductive strategy. 1. B) What type of survivorship curve is demonstrated by Lizard B? Again, describe an advantage and disadvantage of this strategy. Question 2 (2pts); In Data and Graphing 7, you saw how population growth can be limited by both predation and carrying capacity. Imagine that an invasive species of snail arrives on an island. On this island, it has no natural predators. The snall feeds on an uncommon plant, which grows in only a few places on the island. Will the snail experience exponential or logistic growth in the short term? Once the snail has reached all patches of suitable habitat on the island, will it experience logistic or exponential growth in the long term? Explain your answers.
