An extinction of one species could destroy an ecosystem if an animal depended on the extinct animal for food. Then that animal would die off, which could affect even more animals.
All the animals that hunt that one have to find other food, so they go extinct...
lo
Invasive species cause harm to the environment, because their like unknown organisms that exist, and replace original species. I might be able to change the environment/ecosystem.
if it leaves an environmental niche, then another, already existing, species might take that niche; or a new one might evolve to fill it.
it can affect an ecosystem by killing it or burning it
Each organism in an ecosystem relies on many other organisms in order to survive. If even one species disappears, many other species are harmed by that disappearance. If you lose several or many species, then you might lose even more species, simply because those species can't survive without the ones that died out. Then even more species suffer and may disappear, and if enough very important species die out, the whole ecosystem can collapse.
Yes, if you are going to save a species then they might as well be saved from extinction.
EXTINCTION
lo
It would soon loose all its animal species too.
an invasive specie is an animal that is dangerous to an ecosystem. so a snail might be an invasive specie to one ecosystem, but to another, they may be part of the ecosystem. No that is completely wrong a invasive species is a species that came to one place from another place and it doesn't belong Dont listen to that idiot it isn't an invasive species it's from North America and so no it is not. Now theres a real answer.
Well, environmental factors like climate change can cause a species to die out because they were not able to adapt to their environment.

mass extinction: When at least 50 % of the species on Earth go extinct within a relatively short amount of time.
if it leaves an environmental niche, then another, already existing, species might take that niche; or a new one might evolve to fill it.
Partially,because in an ecosystem,animals of similar species. While in another, animals of far different species might be present.
Yea im pretty sure but i might be wrong
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
