Question: Extract the answer to the question from the following context. Question: What type of annelid supports saltwater food chains? Context: Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.
Answer: marine polychaetes

Question: Extract the answer to the question from the following context. Question: Which of the two leagues gets more money due to the loss of TV revenues? Context: The Premier League distributes a portion of its television revenue to clubs that are relegated from the league in the form of "parachute payments". Starting with the 2013–14 season, these payments are in excess of £60 million over four seasons. Though designed to help teams adjust to the loss of television revenues (the average Premier League team receives £55 million while the average Football League Championship club receives £2 million), critics maintain that the payments actually widen the gap between teams that have reached the Premier League and those that have not, leading to the common occurrence of teams "bouncing back" soon after their relegation. For some clubs who have failed to win immediate promotion back to the Premier League, financial problems, including in some cases administration or even liquidation have followed. Further relegations down the footballing ladder have ensued for several clubs unable to cope with the gap.
