Q6.2. Suppose the rate of plant growth on Isle Royale supported an equilibrium moose population of 300 moose. In this scenario, there are no wolves present, and the environment is stable. One day, 200 additional moose arrive on the island. What would you predict the moose population size to be 30 years later? (Enter your answer as a number.) Submit moose

Q3.8. Suppose you are tracking the population size of a herd of bison inside a large protected park in the northern Rocky Mountains. After many years of research, you and your colleagues have estimated the carrying capacity of the park to be 800 bison. Because some bison were recently relocated into the park from elsewhere, the current population size is 900. What do you estimate the size of the herd to be in 20 years, assuming environmental and ecological conditions do not change?
Q6.3. Imagine two new volcanic islands spring up in the middle of the ocean. Each island is quickly founded by a few individuals of a species of aquatic bird that requires an abundance of fresh water to thrive. The two islands differ in rainfall, one much wetter and one much drier. Given that bird carrying capacity is determined by the amount of rainfall, and assuming that rainfall is consistent over time, what might the growth curves for the bird populations look like over many years?

Q6.8. Imagine that after the birds have been living in the city for many years a second big flock of birds arrives. How will the bird population size change in the 10 to 20 years after the extra birds arrive? Choose the graph that best represents how the city's bird population should change over time. (Note: there are still no predators of these birds in the city.) Pop. Size . Pop. Size Time Time Submit Answer saved to SimuText server. Pop. Size Pop. Size Time Time

The diagrams below show very simplified species relationships for certain areas of African savanna. Recall what the direction of arrows means for each type of diagram. Then use these simplified diagrams to answer the next 3 questions. (Note: Real-world savannas support more species with more complex relationships.)

If you removed all the Lions from a large area of savanna, which of the following is a DIRECT effect that could be explained by the diagrams?

CHAPTER LESSON ر2 Limits to Growth READING TOOL Compare and Contrast As you read your textbook, complete the Venn diagram to compare and contrast density-dependent limiting factors and density-independent limiting factors. Density Dependent Limiting Factor Scenario(s) go gniy Limiting Factors limit population size Density Independent bidslas seltsdW.IS Once you have finished the venn diagram, categorize the following scenarios as density-dependent and density-independent limiting factors. Scenario A: A flood wipes out all the plant species that live on a riverbed. Scenario B: A pack of wolves migrates to a new valley and eats all the deer that inhabit that Scenario C: A large population of zebras are killed due to a very contagious virus. Scenario D: A drought kills many of the deer that live in a valley. Density-Dependent Density-Independent space.
