Imagine that you are a scientist studying species interactions in Kruger National Park, South Africa. Today, you are observing a pride of lions in the southeast quadrant of the park. Two lionesses brought down a large adult wildebeest. The adult females fed for approximately 20 minutes. Their cubs appeared interested in feeding but were largely kept away from the kill by the adult lions. A clan of hyenas drove the lions from the carcasses and fed for approximately 30 minutes. Two male lions drove the hyenas from the carcass, killing a female hyena. The male lions ate most of the kill; vultures fed on remains.

- Great white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)You are studying the competitive interactions between largemouth bass and lake trout in a several lakes. Some lakes have both largemouth bass and trout, while other lakes don’t have largemouth bass. You examined the gut content of a large sample of bass and trout. In lakes in which both species are found, 100% of the bass diet is composed of small fish while only 15% of the trout’s diet is composed of small fish. The remaining 85% of the trout diet’s is composed of zooplankton. In the lakes without bass, the diet of the lake trout is composed at 85% of small fish and 15% of zooplankton. What can you conclude from these results? Select one: a. Largemouth Bass will eventually completely exclude Lake Trout from the Lake. b. The absence of Largemouth Bass results in a trophic cascade. c. Largemouth Bass have a greater carrying capacity than Lake Trout. d. Without Largemouth Bass, the trout populations grow exponentially. e. The presence of Largemouth Bass prevents the Lake Trout to…Two related species of salamanders were found living on opposite sides of a mountain. One species lives in along a shady forest stream on the leaf covered-ground and is brown with dark green spots. The other species live along the bright, sandy banks of a larger river is light tan in color. What is most likely cause of the difference between these two species of salamander? Group of answer choices Competition Predation Mating seasons Different habitats
- At the edge of the Arctic Circle, owls prey on field mice. Occasionally, in a litter of white field mice, a brown mouse appears. Because of greenhouse warming, the snow melts, changing the environment to shades of brown. What is most likely true regarding the brown mice before the greenhouse warming? The brown mice population was large in number. The brown mice population was small in number. The fur color of mice changed to white because they needed to survive. There were no brown mice born before greenhouse warming.Do the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.Figure 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.
