input question: This article: The northern gannet is not heavily predated. The only known habitual natural predators of adults are bald eagles and white-tailed eagles. Predators of eggs and nestlings include the great black-backed gull and American herring gull, common ravens, ermine, and red fox. Attacks at sea are insignificant though large sharks and seals may rarely snatch a gannet out at sea.Kleptoparasitism by skuas, particularly the great skua, occurs at breeding sites. The skua chases its victim until it disgorges its stomach contents, providing a meal for the attacker. Skuas may catch the tip of the gannet's wing, causing it to fall into the sea, or seize the tail to tip its victim into the water. The gannet is only released when it has regurgitated its catch.External parasites include feather lice, although there are relatively few species and none are found on the head. As with grebes and divers it may be that the short head feathers provide insufficient cover for the parasite. In one species, Michaelichus bassani, immature lice are found in the membranes lining the subcutaneous air-cells. Ixodes mites include the widespread I. uriae.The spiny-headed worm Corynosoma tunitae appears to occur only in gannets and closely related seabird families such as the cormorants. The tapeworm Tetrabothrius bassani adsorbs toxic heavy metals at a higher concentration than the gannet's own tissues, with an average 12 times as much cadmium as the gannet's pectoral muscles and 710 times the lead level of the bird's kidney and liver. Since levels of these toxic metals are detectable in the parasite earlier than in the host, the tapeworm might be used as an early indicator of marine pollution. contains an answer for the question: Levels of what can be detected earlier in a gannet's tapeworm than it can be in the gannet?, what is it ????
output answer: toxic metals

Problem: Given the question: This article: The Ocklawaha River flows north and joins the St. Johns as the largest tributary, and one of significant historical importance. The Ocklawaha (also printed as Oklawaha) drainage basin expands through Orange, Lake, Marion, and Alachua Counties, comprising a total of 2,769 square miles (7,170 km2). Ocala, Gainesville, and the northern suburbs of the Orlando metropolitan area are included in this basin. There are two headwaters for the Ocklawaha: a chain of lakes, the largest of which is Lake Apopka in Lake County, and the Green Swamp near Haines City in Polk County, drained by the Palatlakaha River. The Silver River, fed by one of Florida's most productive springs expelling 54,000,000 US gallons (200,000,000 L) daily, is located about midway along the 96-mile (154 km) Ocklawaha.Confederate Captain John William Pearson named his militia after the Ocklawaha River called the Ocklawaha Rangers in the American Civil War. Prior to the civil war, Pearson ran a successful health resort in Orange Springs. After the civil war Pearson's Orange Springs resort declined in popularity due to the increasing attention to nearby Silver Springsthe source of the Silver Riverat the turn of the 20th century, popularizing the Ocklawaha. Georgia-born poet Sidney Lanier called it "the sweetest waterlane in the world" in a travel guide he published in 1876. The river gave Marjorie Kinnan Rawlings access to the St. Johns from her homestead at Orange Lake. The region served as a major fishing attraction until a decline in water quality occurred in the 1940s, and since then further degradation of the river and its sources have occurred. In particular, Lake Apopka earned the designation of Florida's most polluted lake following a chemical spill in 1980 that dumped DDE in it. It has experienced chronic algal blooms caused by citrus farm fertilizer and wastewater runoff from nearby farms.The proliferation of largemouth bass (Micropterus salmoides), black crappie (Pomoxis nigromaculatus), and bluegill (Lepomis macrochirus) in central... contains an answer for the question: What two waterways join as the largest tributary?, what is it ?
