Species Introduced by Humans to New Geographic Locations

Question

Species introduced by humans to new geographic locations
A) are usually successful in colonizing the area.
B) always spread because they encounter none of their natural predators.
C) increase the diversity and therefore the stability of the ecosystem.
D) can outcompete and displace native species for biotic and abiotic resources.
E) are always considered pests by ecologists.

Accepted Answer

Species introduced by humans can thrive in a new environment because they often face less competition and fewer predators than in their home environment, enabling them to outcompete and displace native species. This can lead to a decrease in biodiversity and destabilization of the ecosystem.
