- Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.arrow_forwardWhy does the aquarium trade contribute to the introduction of nonnative species? a.

- Part A) A biologist notices that the same species of Tortoise exists in Texas and Mexico.Yet these tortoises have somewhat different life histories. This is probably due to the diverse array of__that each tortoise has with different components its own environment.a. interactionsb. conversationsc. adaptationsd. all of thesePartB.). If water amounts and food production capabilities decrease, what can happen to carrying capacity?a. increase b. decreasePart C. Alabama should be a desert but it is a lush green environment. What keeps us from being so dry?a. Hadley Cellsb. Ocean Gyresc. Mountainsd. all of the abovearrow_forwardRefer to the figure below to answer the question that follows. Plant Butterfly Rabbit Rat 49. In response to an increase in the eagle population, a. the rat population would increase. b. the butterfly population would increase. c. the rabbit population would increase. d. the lizard population would increase. the snake population would increase. e. - Lizard Snake Eagle 6arrow_forwardCarrying capacity is defined as a species’ average population size in an environment. Which of the following resulted to exceeding carrying capacity in a particular environment? a. increasing birthrates, decreasing deathrates, increasing immigration and no emigration takes place b. increasing birthrates, decreasing deathrates, decreasing immigration and no emigration takes place c. increasing birthrates, decreasing deathrates, decreasing immigration and increasing emigration d. decreasing birthrates, increasing deathrates, increasing immigration and increasing emigrationarrow_forward
- Which of the following events would not negatively impact Yellowstone’s grey wolf carrying capacity? a. snow in winter b. a beaver damming a river upstream c. a forest fire d. chronic wasting disease in the deer populationarrow_forwardIf populations of white rhinoceros (Ceratotherium simum) continue to decline, one approach to prevent extinction would be captive breeding. How does this process work? a. The remaining animals are moved into captivity to try to increase the population, after which they are reintroduced into the wild. b. The remaining animals are moved to a national park. c. The remaining animals are taken to the largest zoos so more people can see theam. d. A few individuals are moved to an outdoor enclosure to ensure that mates are available.arrow_forwardUse the following simple predator-prey relationships to answer the questions about the system below (assume no other interactions exist in this system). Mice eat grain grown by a farmer before it can be harvested. The mice are consumed by several species of snakes, which themselves are consumed by hawks. A. If the population of snakes was suddenly wiped out by disease, explain the short-term effects on the grain, mice, and hawk populations, and why these effects would be observed. B. If the population of snakes were suddenly wiped out by disease, explain the long-term effects on the grain, mice, and hawk populations, and why these effects would be observed. C. Local farmers would like to use a biological, as opposed to a chemical, means to protect their crop. What would be the most effective way for farmers in this area to protect their grain crop naturally? Why? Edit View Insert Format Tools Table 12pt ✓ Paragraph BIUA V 2 ✓ T² v :arrow_forward
