A researcher studying a population of antelopes developed the life table shown below. Use this table to answer the following questions. Life Table Age sx bx 0 0.4 0 1 0.3 0 2 0.9 1 3 0.8 3 4 0.1 2 5 0.0 0   What is the survivorship of an individual from birth to the age of 4 years? (4.0 pts) must show work to receive full credit. What is the net reproductive rate of the population? (5.0 pts) must show work to receive full credit. Do we expect this population to increase, remain relatively the same, or decrease? Why? (3.0 pts) describe both numerically and with text. must show work to receive full credit. To ensure accurate grading, label the three question a, b, and c in your answer.

The food web below displays the direct and indirect effects that fish, dragonflies, bees (i.e., pollinator), and plants have on each other. Describe three (3) of the seven (7) interactions between these five organisms. The interactions are denoted by the seven arrows. In each description, state: the names of the two organisms (e.g., larval dragonfly affects plants) if the effect is direct or indirect if the effect is positive or negative what happens during the interaction (e.g., the adult dragonflies eat the grass). *Note: you are expected to describe 3 different scenarios for full credit. Each scenario is worth 2.0 pts and each must contain the four points described above. *You can combine parts 1-4 as you see fit in your writing to reduce redundancy, just be sure all required parts are in your answer.

Explain your answer (2.0 pts)

Consider what we have learned about predation and how they limit the abundance of prey. Compare and contrast native species, introduced species, and invasive species (8.0 pts) Why are native species (i.e., prey) often overwhelmed by invasive predators? (2.0 pts)
