Final answer:
The introduction of an invasive species can disrupt ecosystems and potentially lead to the extinction of native species, by out-competing them for resources or spreading new diseases.
Step-by-step explanation:
The introduction of a novel organism into an ecosystem, particularly one that becomes an invasive species, can indeed lead to negative consequences, including the possible extinction of native species. Invasive species are capable of disturbing the natural balance by competing with native species for resources, predating on them, or spreading novel diseases. Such disruptions can result in reduced biodiversity, altered community structures, and at times, the local or complete extinction of indigenous species. Therefore, to address the student's question, the statement that the introduction of a novel organism into an ecosystem can lead to the extinction of species is true.
