Question

Non-native species:
Invasive species:

A: not indigenous
B: harmful to indigenous species
C: not harmful to indigenous species
D: Can cause species to go extinct

Answer 1

Non-native species and invasive species both refer to species that are not indigenous to a specific ecosystem or region. However, invasive species are specifically characterized by being harmful to indigenous species. They can outcompete native species for resources, disrupt the local ecosystem, and potentially lead to the extinction of native species. Non-native species, on the other hand, may or may not have a negative impact on indigenous species. They can coexist with native species without causing harm or disruption to the ecosystem. Overall, invasive species are considered a greater threat to biodiversity and ecosystem health compared to non-native species.
