The world's largest organism is a fungus in Oregon. This fungus stretches 3.5 miles (5.6 Km) across and covers an area as big as 1,665 football fields. It is about 2,400 years old, lives underground, and spreads slowly from tree to tree.

What is probably the largest living organism on earth has been discovered in the Malheur National Forest in eastern Oregon. A fungus living three feet underground is estimated to cover 2,200 acres. After testing samples from various locations, scientists say it is all one organism.
One Thousand Football Fields

Officially known as Armillaria ostoyae, or the honey mushroom, the fungus is 3.5 miles across and takes up 1,665 football fields. The small mushrooms visible above ground are only the tip of the iceberg.

Experts estimate that the giant mushroom is at least 2,400 years old, but could be 7,200 years old.

Previously, the world's largest organism was another Armillaria ostoyae, which covers a mere 1,500 acres near Mt. Adams in Washington state.
A Web of Tentacles

Scientists became interested in that section of forest when trees began to die. The honey mushroom uses tentacles, called rhizomorphs, to take water and nutrients from roots, killing trees.

The process benefits the ecosystem by creating clearings where new plants grow. Animals, such as woodpeckers, live in the dead tree trunks. Mushrooms also recycle nutrients
Dry Climate Helps

The dry climate of eastern Oregon discourages competition from new growth, leaving space for mushrooms already established.
Genetically Closer to People

In other research, scientists have determined that fungi are more closely related to human beings and animals than to other plants.

Moreover, while humans and most species are divided into only two sexes, mushrooms contain over 36,000 sexes.

Animal is a female blue whale, the largest animal ever found on Earth.

Plant is more difficult. The largest single organism is probably a giant redwood tree. However, some fungi can spread for enormous disatnces underground.

The Aspen Tree "Pando", that is proper underground by a enormous community of roots, by mass a minimum of, that is the 'best' in words of heaviest, common organism contained in the international. observe: The Honey Fungus pronounced is idea to be the biggest by section yet disputed because that is believed purely 20-30% of the fungi is idea to be completely proper by the mycelia, meaning it isn't a unmarried proper clonal organism. There hasn't been sufficient study into the Honey Fungus of the Blue Mountains to examine no matter if that is in truth the biggest unmarried organism. hence that is speculative. the final Sherman tree is the biggest unmarried stem tree in words of quantity, in words of height that is Coast Redwood. purely idea i can make this observe because of the contrariety of solutions and the unknown definition you meant by best.

It is a whale. Definitely a whale because the Whale is the largest living thing, and an organism is a living thing.
