A microbe from an ecosystem that exists in the same arctic region has infected the whale population. The graph below shows the new carrying capacity for the whale population. N represents population number, t represents time, and K represents carrying capacity. Explain how these microbes have affected the whale population. Does this new evidence change the seal and killer whale relationship? Does this new relationship represent a sigmoid or peak phenomenon? Please provide supporting details. If scientists added a chemical to destroy the arctic microbes, what positive and negative consequences could result? What population settings could you adjust in the simulation to test components of this solution? Climate change in the form of global warming (an abiotic factor) has slowly decreased habitat for the arctic seals. What are the limitations of the population dynamics simulation in predicting the changes that may occur due to climate change? Imagine that all nations agreed to reduce greenhouse gas emissions by half in an effort to reduce global warming. In what ways could you revise this simulation, so it accounted for the influence of this solution on arctic habitat, and on the whale and seal populations?
