Question

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

Answer 1

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

This distinction highlights that while introduced species can often be benign and integrated into their new ecosystems without causing harm, invasive species typically disrupt local ecosystems, outcompete native species, and lead to ecological damage.
