It has no predators in the new ecosystem.
It has no predators in the new ecosystem.
It is harmful to organisms in all ecosystems.
It is harmful to organisms in all ecosystems.
It is from a different ecosystem.
It is from a different ecosystem.
It does harm and is introduced to the ecosystem.
It does harm and is introduced to the ecosystem.
The correct response is: "It is from a different ecosystem." Invasive species are typically introduced to a new ecosystem where they are not native, and their introduction can cause harm to the existing ecosystem's native species and overall biodiversity.
The correct response is: It does harm and is introduced to the ecosystem.
The correct answer is: "It does harm and is introduced to the ecosystem."
When an organism is considered an invasive species, it means that it is not naturally found in a particular ecosystem and has been introduced there by human activity. The introduction of the invasive species to the ecosystem can be intentional or unintentional.
The reason why an invasive species is harmful is because it tends to have no natural predators or control mechanisms in its new environment. This lack of natural checks and balances allows the invasive species to reproduce rapidly and outcompete native species for resources such as food, water, and habitat.
The harmful effects of invasive species can be seen in various ways. For example, they may outcompete native species for resources, disrupting the natural balance of the ecosystem. They may also prey on or parasitize native species, leading to a decline in their populations. Invasive species can also alter the physical environment of the ecosystem by modifying habitats or outcompeting native vegetation. This can have cascading effects on other organisms that depend on those habitats.
Overall, the combination of doing harm to the ecosystem and being introduced into it is what defines an organism as an invasive species.
