On a certain island new species are being introduced at a rate of
species per year.
But conditions cause species extinction at a rate of
species per year.
Here t is the time in years. Equilibrium occurs when the rate of extinction is the same as the rate new species are being introduced.A: The time when equilibrium occurs is the solution of an equation. Which equation?B: Plot the graphs of both N and E on the same coordinate axes over the first 10 years of activity.C: When does equilibrium occur? Round your answer to two decimal places.D: What is extinction rate when equilibrium occurs? Round your answer to two decimal places.
