Descent with modification
Totally there are more than 5 million species living in the earth , in that 67 percentage are living as water species , so the remaining are land species.
Non-native species affect an ecosystem because they are organisms that are living outside of their natural range. This non-native species is a lot like pollution. It can harm or destroy native species because they compete or hunt for their food and water. Hope this helps!! :)
When an environment is disturbed, changes are seen in more sensitive organisms before the effect become apparent in less sensitive species. These organisms, usually plants or microorganisms, are called indicator species or bio-indicators.
Isn't that a flower though?. What do you mean how many living species are there in Magnoliophyta?.
an organism is 1 living species and species are things that live in a certain area

The theory that living species were descend with changes from other species over time is referred to as evolution.
Modification:p hope this helped
They can't. Once a species becomes extinct, it has reached the end of the line. It no longer exists, so therefore produces no more offspring. Thus, the theory that living species of today are descended from extinct species from long ago is untenable.

I believe that it is the principle of evolution.
The closest living species related to the cheetah are the cougar and the jaguarundi. All are descended from a common ancestor in North America.
Fossil species cannot be defined with the genetic definition. But then that's also true of most of the species that biologists define among living organisms.
