The levels of an environment to be organized are populations,species,community,and the ecosystem
Species make up populations, which make up communities.species make up communities,which make up populationsspecies are grouped in populations, which make up communities
Trying to control an introduced species can keep the populations down on overpopulated creatures and keep the ecosystem stable. It can also be bad if the species gets over hunted and populations get low.
A new species, when introduced to an ecosystem, will compete with the indigenous species for food and resources. If the new species is predatory, it may also begin preying on the indigenous species, so the native populations will decrease sharply.
it is a community
The keystone species in any given community protect other species from their predators, so that those species are able to function correctly and do their jobs, or add their contribution to keep the ecosystem up and running.
