Please answer this: Question: "What was the outcome after the wolf population dropped?" 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: profound impacts on the trophic pyramid

Problem: Question: "What are chinese characters made out of?" Context: "Examples are he "river", hu "lake", liu "stream", chong "riptide" (or "flush"), hua "slippery". All these characters have on the left a radical of three short strokes (), which is a reduced form of the character shui meaning "water", indicating that the character has a semantic connection with water. The right-hand side in each case is a phonetic indicator. For example, in the case of chong (Old Chinese *-lju), the phonetic indicator is zhong (Old Chinese *k-lju), which by itself means "middle". In this case it can be seen that the pronunciation of the character is slightly different from that of its phonetic indicator; the process of historical phonetic change means that the composition of such characters can sometimes seem arbitrary today." Answer:

A: radical

Problem: Given the question: Question: "What is the term used for the average income such as that of Switzerland?" Context: "The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP per capita). In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. Switzerland also has one of the world's largest account balances as a percentage of GDP." Answer:

input question: Question: "What is a major problem in LEDs, that leads to efficiency loss?" Context: "Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness." Answer:???
output answer: internal optical losses
