It is harmful to organisms in all ecosystems
It has no predators in the new ecosystem
It does harm and is introduced to the ecosystem

Answer 1

The aspect of an organism that makes it an invasive species is when it does harm and is introduced to a new ecosystem. This can lead to negative impacts on native species, habitats, and ecosystems, often outcompeting native species for resources and disrupting the balance of the ecosystem. Additionally, invasive species often lack natural predators in their new environment, allowing them to rapidly multiply and spread.
