Question: Question: "Wolves engage in?" Context: "The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place." Answer:
Answer: predation

Question: Question: "What contributes to the island's climate?" Context: "The climate of Saint Helena is tropical, marine and mild, tempered by the Benguela Current and trade winds that blow almost continuously. The climate varies noticeably across the island. Temperatures in Jamestown, on the north leeward shore, range between 2128 C (7082 F) in the summer (January to April) and 1724 C (6375 F) during the remainder of the year. The temperatures in the central areas are, on average, 56 C (9.010.8 F) lower. Jamestown also has a very low annual rainfall, while 7501,000 mm (3039 in) falls per year on the higher ground and the south coast, where it is also noticeably cloudier. There are weather recording stations in the Longwood and Blue Hill districts." Answer:

Question: Question: "When is Atticus the most vulnerable?" Context: "The theme of racial injustice appears symbolically in the novel as well. For example, Atticus must shoot a rabid dog, even though it is not his job to do so. Carolyn Jones argues that the dog represents prejudice within the town of Maycomb, and Atticus, who waits on a deserted street to shoot the dog, must fight against the town's racism without help from other white citizens. He is also alone when he faces a group intending to lynch Tom Robinson and once more in the courthouse during Tom's trial. Lee even uses dreamlike imagery from the mad dog incident to describe some of the courtroom scenes. Jones writes, "[t]he real mad dog in Maycomb is the racism that denies the humanity of Tom Robinson .... When Atticus makes his summation to the jury, he literally bares himself to the jury's and the town's anger."" Answer:
Answer:
When Atticus makes his summation to the jury
