Question

what do scientists call a non - native species that reproduces quickly and spreads in an environment when these organisms can cause harm to an ecosystem?
a competitive species
a displacing species
a persistent species
an invasive species

Explanation:

Invasive species are non - native and can rapidly reproduce and spread, causing harm to ecosystems. Competitive species compete but may not be non - native and harmful in this context. Displacing species is a less formal term and not the standard scientific one. Persistent species may just be long - lasting but not necessarily non - native and harmful as described.
