What would happen if an invasive species was introduced to the community?
Invasive species may outcompete native species for resources or habitat, altering community structure and potentially leading to extinctions.
Why invasive species thrive at the expense of native species?
Many invasive species thrive because they outcompete native species for food. There are now so many carp in the lower Missouri River that paddlefish do not have enough food. Invasive species sometimes thrive because there are no predators that hunt them in the new location.

How do invasive species affect population?
Since invasive species are in a new environment, free from natural predators, parasites, or competitors, they often develop large population sizes very rapidly. These high populations can out-compete, displace or kill native species or can reduce wildlife food and habitat.
What will most likely happen if an invasive species is introduced into a stable ecosystem?
What will most likely happen if a nonnative species is introduced into a stable ecosystem? The native species will move to another area, and the ecosystem will remain stable. The native species will have to compete for resources with the nonnative species, and the ecosystem will become unbalanced.

How do introduced species affect the environment?

How many introduced species are in the US?
