Humic acid is a principal component of humic substances, which are the major organic constituents of soil (humus), peat, coal, many upland streams, dystrophic lakes, and ocean water.t is produced by biodegradation of dead organic matter. It is not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid.

On average, polar bears on all fours are 3.5 to 5 feet (1 to 1.5 meters) tall, but when standing on its hind legs, an adult male polar bear may reach more than 10 feet (3 m). Lengthwise, they are 7.25 to 8 feet (2.2 to 2.5 m) from head to rump. Their tail adds another 3 to 5 inches (7.5 to 12.5 centimeters). An adult male polar bear weighs around 775 to 1,200 lbs.
