Every organism can become extict at any time. For example, the dinosaurs were extict when the comet hit the earth and killed the whole population.
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
Neither. The leaves of the tree represent descendants; the root or base represents the common ancestor of all organisms in that tree. This says nothing about which have survived and which have become extinct, only which appeared first and which developed from it.
when there are no living members of a species the species is said to be "extinct".
Extinct.
overpopulation
what happen when some living organisms in food phyramid become extinct
Few organisms have become extinct. Few organisms are rare species.
Extinct (Extinction)
alive
By the way they look, (their bone structure, body weight) and DNA too.
The study of how living and extinct organisms are related to one another is simple. This study is called evolution.
You obviously hadn't noticed that living things have not become extinct. There are still plenty of them about.
The sun is not alive, only living specis can become extinct.
They become extinct.
All the ones not extinct.
The are examples of stromatolites still living. They are not extinct.
The Antarctic Treaty is a TREATY not a living thing so it can not become extinct.
