The largest numbers of species of organisms on the earth are currently bacteria. They out number plants and animals by far.
wind is created by the uneven heating of the earth's surface. so i don't think that there is a cell that is responsible for the formation of wind.
The formation of life on earth has little to do with evolutionary sciences, which deal how lifechanges, not how it begins. The formation of life has as little to do, specifically, with evolution as it does with cell theory, or biogeography, or diet of organisms, or photosynthesis... it's a prerequisite for these processes.
Reproduction is the life process which ensures that a plant or animal species will not disappear from the earth
All species have a purpose to the eco-system (Excluding Humans), due to the food chain and jobs that the species has to achieve. Here are 2 examples, one of its job, and another of a food chain: Bees are crucial to the living of earth, as they allow plants to grow using pollination, without bees earth would die out because of the lack of food for Mammal vegetarians, as this would affect Mammal herbivores because of the food chain (Herbivore eats Vegetarian) Worms die out, therefore destroying the food chain, (Worms<Birds<Large mammals<ECT...

Mass extinction
Extinction is when a species is completely gone from everywhere on Earth. Extirpation is when a species is completely gone from one area, but still exists in other parts of the world.
just about every one. 90% of all creatures that have lived on earth are extinct.
george cuvier, french scientist, examning the fossil-laden rock of the Paris Basin early in the nineteen century, provided conclusive evidence of the extinction of species on earth.
An extinct animal is an animal that has no living member on Earth i.e. all of that species have died.
These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.
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.
1000
This would be called a mass extinction or mass die off.This would be called a mass extinction.
