Upwards to the trillions.
The National Science Foundation's "Tree of Life" project estimates that there could be anywhere from 5 million to 100 million species on the planet, but science has only identified about 2 million.
There are many species of horses that are alive and inhabit the Earth today. There are domesticated horses that are well taken care of, and feral horses that roam the Earth, there is an estimated 59,000,000 horses in the world.
As of 2012, the estimated population of France is 65,350,000.
Earth is estimated to contain around 8.7 million species, but there could be many undiscovered species. The total biomass of all living organisms on Earth is estimated to be around 556.7 billion metric tons.
about 60 billion people! well by now a bit more than that------------------------------------------------------------------------That's incorrect if I may put it bluntly.There are currently around 7.000.000.000 (7Billion) human beings living on Earth but I believe that was not his/her question.If you mean how many living beings (as in "living organisms") are estimated to inhabit the earth, including bacteria, then the answer is 3 X 10 to the 33rd power (3,000 quintillion, 3X10^33) and around 75% of that is bacteria.IT--
It is estimated that there are around 1030 cells on Earth.
Scientists have discovered and described approximately 1.75 million species of organisms. However, it is estimated that there may be as many as 8.7 million species on Earth, meaning that many more species are yet to be discovered.
Scientists have identified and named around 1.7 million species of organisms, but it is estimated that there may be anywhere from 8.7 million to over 1 trillion total species on Earth.
Insects (like beetles, butterflies, ants) have the largest number of species on Earth, estimated to be around one million. Bacteria and archaea are also very diverse groups, with millions of species estimated to exist, although many are still undiscovered and unstudied.
There are an estimated 8.7 million species of organisms on Earth, although the actual number could be much higher. This includes a wide range of organisms such as bacteria, fungi, plants, animals, and protists.
Yes, many living organisms inhabit the lithosphere, including organisms such as plants, animals, and microorganisms. These organisms interact with the rock and soil of the lithosphere to derive nutrients and support their survival.
There are estimated to be around 198,000 glaciers on Earth.
