Most invasive species spread in groups (as long as its not just one) and because of this the males and females are enabled to have an offspring which can produce more offspring and before you know it 12 lizards can turn into hundreds.

Alien and invasive species affect the biodiversity of a area because the species keeps spreading and soon it is everywhere. Then they change the amount of resources in a area. So the other plants die and and then the animals who eat those plants die too and so on. This is how a species can affect a whole forest or biodiversity.
Of course there are. Some are just because of deforestation by humans, and weeds (the invasive species) occupying that area, ensuring that the rainforest can never come back in that area.
Invasive species have such an impact on the environment because they basically have no naturally known enimies. If they come from a different land, the organisms that are already living there aren't used to the envasive species being there, and have no natural defense against them. The invasive species will devour all it wants, and can wipe out an entire population of a species in an area.
Forests are home to a number of diverse species. When the area is changed in any way, the number of species that can thrive there changes.
Well, it depends on which location you want to know about.There are many animals affected by invasive species. But the animals affected are the ones in the area of the invasive species(s) . =D
Invasive species are species that are not native to an area. They typically will thrive in their new environment and in doing so will change the ecosystem by starving out the native species. Some examples of invasive species in America are Japanese beetles, Asian carp, kudzu, phragmites and many many more.
No.To be an Invasive Species the animal must not be in the area before.Displace a species or multiple species from the area.Bald eagles do neither.
invasive species.
Invasive species of plants or animals can cause a disruption in the natural food chains of a particular area. This can lead to the dying off of species normally found in that area.
habitat
A new species entering a geographical area is called and invasive species. These new species may soon take over since they may not have any natural predators, or enemies.
A species is not inherently native or invasive. All species on Earth have a region to which they are native. If they are introduced to a new area, then they are invasive to that area. The orca has a cosmopolitan distribution, so it is native to oceans pretty much everywhere.
It's an environment they can thrive in, and they don't really have any natural predators in the area. Not to mention idiots keep letting them loose in the Everglades.

Invasive species disrupt the natural order of an area. They do not have natural predators, hunt and kill animals that would feed the predators native to an area, and in some cases, can cause a complete collapse of the local ecosystem.
