- Rajah pitcher plants in Borneo may obtain most of the nitrogen they need from the scat of mountain tree shrews and summit rats, both of which eat pitcher plant nectar. The plants get the rest of their nitrogen from insects they capture and digest. Insects are scarce in the plants' mountain habitat and some plants may get all their nitrogen from scat. Which graph depicts what would most likely happen to the rajah pitcher plant population were the mountain tree shrew and summit rat to go extinct? Option A Time Option D O Option B O Option C C Option A Option B Option C Option Darrow_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 them. d. A few individuals are moved to an outdoor enclosure to ensure that mates are available.arrow_forwardScientists have observed a trend in population changes of the snowshoe hare in Canada. About every 8 years, the number of hares falls sharply. One year later, the number of lynx in the same area falls also. The lynx is the main predator of the snowshoe hare. Scientists discovered that snowshoe hares rely on willow plants for food during the winter. When the snowshoe hare population gets bigger, they eat more of the leaves on the willows. Scientists also found out that willow plants release a poison when they get eaten back too far. Which statement best describes what limits the size of the snowshoe hare population?arrow_forward
- Dippers (Cinclus cinclus) are small birds that can be found along fast-flowing streams in Europe and Asia. They feed on insect larvae, especially those of caddis flies (Trichoptera), which they catch by sticking their heads under water and turning over stones. Describe the relationship between the abundance of caddis fly larvae and dippers?Why, is caddis fly larva abundance expressed as ‘relative abundance’? using the data in Table 2arrow_forwardImagine the birds that eat peppered moths went extinct. What would happen to the peppered moth population?arrow_forwardWhy were small-beaked medium ground finches (Geospiza fortis) most affected by the drought on Daphne major in 1976? A. Being small, they were less able to withstand the high temperatures during the drought B. The type of food that they eat, insects, was depleted C. Their beaks were too small to eat the remaining food, large nuts D. Their territory was taken by large-beaked medium ground finchesarrow_forward

A. Species coexistence requires that the two isoclines cross. B. The crossing of the two isoclines is a sufficient condition for species coexistence. C. If the species coexist, they will each do so at a higher density than either would if placed alone. D. Strongly competing species can only coexist if the two species have very different carrying capacities. E. Coexistence will occur if the two isoclines are parallel.arrow_forward
