When there is ABSOLUTOLY NONE left of that organism then it is extict meaning it will NEVER come back!
It depends on the organism.
It is an extinct organism.
the organism has to reproduce otherwise the species will go extinct.
it depends on what organism
for something to be come pletle extinct.
We call such past organism "extinct".
The word "extinct" is an absolute modifier; it does not come in varying degrees. An organism is either extinct or it isn't. One thing cannot be more extinct than another.
You can't. If a species is extinct, that means that no organism in that species is alive. It is gone forever.
extinct
If an organism becomes extinct, its predators may struggle to find alternative food sources, leading to population declines or shifts in their feeding habits. This can have cascading effects on other species within the food web, potentially disrupting the balance and stability of the ecosystem.
Any living thing can become extinct.Extinct means that this organism no longer exists. This can happen to any type of living organism(or non-living organism, if you are talking about viruses). if you are refering to a human being the person has to die before that person is extinct
The most directly affected of the food chain would be on the organism that used to eat the extinct animal and whatever the extinct organism used to eat. The whole entire food chain is ultimately affected.
