New competitors

New competitors
In ecology, the principle of competitive exclusion is the idea that two species competing for the same limited resource cannot coexist at constant population values. If one species has a smaller advantage than another, the dominant species will prevail in the long run. This leads to the extinction of the weaker competitor. This principle is expressed in the sense that "complete competitors cannot live together."

How can competition cause species to become extinct?

competition often leads to extinction. Less adapted species may receive less of the resources that both species need. As a result, members of this species are less likely to survive and the species may become extinct.
Why is competition important to species?
As the environment changes and new factors are added to the ecosystem, these pressures influence organisms to change, thereby making them better competitors. Competition plays a very important role in ecology and evolution. The best competitors are the ones that survive and pass on their genes
Are species harmed by competition?
Competition: : one species benefits, the other harms.

Examles
In the 1940s brown tree snakes were accidentally introduced to the island of Guam in the western Pacific Ocean. Since then scientists think that the snacks have caused the extinction of at least ten native bird species
