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.
Scientists have identified more than 3 million types of organisms on earth
5-100 million
That answer is still unknown to mankind.
Biodiversity......at least i think so :)
No. The mantle is made of rock and nothing lives there. The biosphere consists of the life on Earth.
No. Orangutans (Pongo spp.) inhabit tropical rainforest with no seasonality. Thus, as there is no winter, there is a year-around food source and stable temperatures, and the orangutan does not need to hibernate.
As they live the organisms comprising a species will age and die, they therefore need to reproduce (have babies) in order to replace the members of the species that die or the species will cease to exist (become extinct).
This topic is debated but here is the most likely cause: Those organisms reproduced and created more organisms. Over time the organisms changed (due to the Earth changing). The organisms reproduced with other organisms and created a new species. After millions of years, creatures like wolves and humans now exist. Hope I helped
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
Upwards to the trillions.
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.
No. The term species denotes a very specific group of organisms. It is estimated that the average extinction rate on Earth is roughly one species per year. Currently it is much higher.
No, he recognised that species evolve into new species.
The largest numbers of species of organisms on the earth are currently bacteria. They out number plants and animals by far.
80%
1,800,000
Gamma rays are not necessarily harmful to the planet Earth, but to all the living organisms that inhabit it, as Gamma is a powerful form of radiation.
we inhabit 89% of earth's thickness
There is an estimated amount of about 7 billion covenant units, about the same as Earth.
All organisms use the same genetic code.Living organisms are made of the same components as all other matter, organisms that inhabit the earth at any one time they are all assembled from a nucleic acid code
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--
