Question

a family introduced their pet fish family into a local pond. the fish had no known local population. the impact of the fish on the ecosystem is not yet known.
which term would best define the fish added to the pond?
○ invasive species
○ introduced species
○ native species
○ symbiotic species

Explanation:

• Invasive species: Harmful, non - native, and spread rapidly. But here the impact is unknown, so not invasive yet.
• Introduced species: Species moved to a new area by human activity, which matches the fish added to the pond (no known local population before).
• Native species: Species that naturally occur in the area, which is not the case here.
• Symbiotic species: Involves a symbiotic relationship, not related to being added to a new area.

Answer:

B. introduced species
