Invasive species are species that have been introduced into a new area they have never been to before. They tend to do very well compared to the indigenous species in that particular area. This results to various negative outcomes to the species in the ecosystem.
They share some similarities but interact differently with the ecosystem.
Invasive species can be confused with the exotic species as they are both non-indigenous species. They are both species that have introduced to a new area they aren’t native to. Invasive species tend to displace the native species and even alter the entire ecosystem. While the exotic species tend to lend in causing no harm to the native species.
They are able to spread faster. This helps them compete for resources that are already scarce. As a result, the productivity of the indigenous species is decreased.
These species tend to attack an already weak ecosystem. They create an imbalance in the ecosystem that is already vulnerable.
These species always dominates where they go. By doing so, they eliminate or reduce indigenous species populations. For instance, the common carp fish caused a serious decline of tilapia fish in Lake Naivasha. The decrease of tilapia affected fish production from this lake.
Their ability to colonize an area they occupy cause a decrease in the native species. With reduced populations and insufficient resources, the native species are vulnerable to endangerment.
