- What happens to the Moose population when the amount of Wolves increase?Why does the wolf population affect the vegetation and vice versa?What would happen to the moose population if the wolves were removed from the island? What happens to the population of wolf if the moose population will decrease? Identify 2 possible limiting factors that have influenced the wolf population?
- How many lions do you think there are in 1960 and 1975? Why do you think the population is the size you predicted?You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America. Which of the following could be a possible factor for the increase in the grizzly population? Loss of habitat Reduction of resources Increased industrialization Higher birth rate over death rateFigure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.
- The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?How many lions do you think there are in 1960 and in 1975?Is the changing buffalo population size caused by a changing predator population size?”
- The population of salmon in Lake Maria has remained constant, at around 2,000 for the past 10 years. Mr. Trout, the owner of the fishing resort on the lake, wants to increase the number of salmon available for his clients to catch fishing. He plans to stock the lake with 1,000 more salmon. Explain to Mr. Trout what will happen to the lake and the salmon population if he adds 1,000 extra fishWhat do you think would happen to the mouse population if the number of fox predators, such as wolves, increased? O If the number of fox predators increases, then there would be more foxes, and the number of mice would increase. O If the number of fox predators increases, then there would be less foxes, and the number of mice would decrease. If the number of fox predators increases, then there would be less foxes, and the number of mice would increase. nothing will happen.Imagine you were the manager of a national park with cheetahs. The cheetahs feed primarily on gazelles, while the gazelles eat grass. It takes an acre of grassland to feed one gazelle, and it takes ten gazelles to feed one cheetah. You have a maximum of ten cheetahs when the system is functioning optimally. You would like to increase the cheetah population because people pay money to see the cheetahs. How much grassland do you need to double the cheetah population supported by this grassland? Select one: A. 500 acres B. 100 acres C. 400 acres D. 200 acres E. 10 acres
