Ants have colonised almost every landmass on Earth. Their population is estimated as between 10 16 –10 17 (10-100 quadrillion). [29] With an estimated 20 quadrillion ants their biomass comes to 12 megatons of dry carbon, which is more than all wild birds and non-human mammals combined. [30] [31] [32]
Seven leafcutter ant workers of various castes (left) and two queens (right) In the colonies of a few ant species, there are physical castes—workers in distinct size-classes, called minor (micrergates), median, and major ergates (macrergates). Often, the larger ants have disproportionately larger heads, and correspondingly stronger mandibles.
Treebeard, called by Gandalf the oldest living Ent and the oldest living thing that walks in Middle-earth, [T 1] is described as being around 14 feet (4 m) tall, "Man-like, almost Troll-like", and clad in something that might have been tree-bark, with seven toes, a bushy, "almost twiggy" beard and deep penetrating eyes.
As scientists have discerned from fossil records, species on Earth have already passed through five mass extinction events in the planet’s lifetime, including the last mass extinction roughly 65 ...
A May 2016 study based on scaling laws estimated that 1 trillion species (overwhelmingly microbes) are on Earth currently with only one-thousandth of one percent described, [28] [29] though this has been controversial and a 2019 study of varied environmental samples of 16S ribosomal RNA estimated that there exist 0.8-1.6 million species of ...
Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 are extant and four subfamilies are extinct , described from fossils .
Using the Federal Reserve’s $2.3 trillion M0 currency figure and a current world population of 8.17 billion, per Worldometer, there’s about $282 per person in the world, on average. Using the ...
The colony was estimated to contain 306 million worker ants and one million queen ants living in 45,000 nests interconnected by underground passages over an area of 2.7 km 2 (670 acres). [14] In 2000, an enormous supercolony of Argentine ants was found in Southern Europe (report published in 2002). [ 15 ]
