Some of the biological effects of introduced species on the Pacific coast would be the imbalance of the food chain, taking over native species and making them endangered of other native species as food and space becomes limited.8. Some of the biological effects of introduced species in Tennessee would be ecosystem destruction resulting in overpopulation of some species, increase in new diseases, damage to the food chain, native species competing for food and space. Questions for discussion:1. Bioterrorism is definitely possible as it is easy for someone to secretly introduce a foreign species.2. If the codes and regulations regarding foreign species that can be imported into the country were stringent, this would not be possible. But if they weren't so strict, then it would be possible.3. Some modes of bioterrorism could include the introduction of foreign species or pests that can cause damage to agriculture resulting in decreased food production, resulting in famine, other foreign species that can endanger or threaten the survival of native species.4. We could protect our environment by imposing even stricter import regulations, proactively assessing risks or side effects before introducing foreign species, requiring an environmental safety check when importing non-native species.
