Question

What is the difference between an introduced and an invasive species? (1 point)
• An introduced species is new to the ecosystem; an invasive species has been there a long time.
An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.
An introduced species is added in by humans; an invasive species enters new ecosystems on its own.
• An introduced species is brought in on purpose; an invasive species is brought in by accident.

Answer 1

The correct answer is: **An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.**

Introduced species can be beneficial or neutral in their new environments, while invasive species cause harm by disrupting ecosystems, outcompeting native species, or causing other environmental problems.
