Since food and other resources are limited, the members of a species must compete with each other to survive. Competition does not always involve direct physical fights between members of a species. Instead, competition is usually indirect.
When species compete,one species is going to eventually lose and die.
Customs checks help stop non-native species from invading and disrupting the native ecosystem. The invasive species may out compete the local species, or the invasive species may have no predators in the native ecosystem.
The fish shares a niche with another species
If species disappeared from an ecosystem the balance in the ecosystem will be altered.
keystone species is a species that has an unusually large impact on its ecosystem.
Typically, the species that it ate overpopulate, and the ecosystem is disrupted.

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.
compete for food
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!! :)
3.One species may be eliminated from that ecosystem
The fish shares a niche with another species
Survival
If species disappeared from an ecosystem the balance in the ecosystem will be altered.
Organisms all want the same resources.
Every organism has a unique ecosystem within which it lives. ... All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space
keystone species is a species that has an unusually large impact on its ecosystem.
Usually animals of the same species compete for mates { two males usually compete over one female.} Animals could compete over prey or vegetation too.
