Case 1: The biome of a small agricultural community in the western United States changes from grassland to desert. A species of migrating duck, which can carry bird flu, goes locally extinct.
Case 2: The biome in northern Russia changes from tundra to taiga. Timber harvesting in the region becomes possible. Arctic foxes go locally extinct and are replaced by red foxes that commonly carry rabies.
Sort the consequence based on whether it would apply to Case 1, Case 2, or both: agricultural production decreases
The consequence "agricultural production decreases" would apply to Case 1.
In Case 1, the change from grassland to desert would likely lead to a decrease in agricultural production due to the loss of suitable land for farming.
In Case 2, while the biome is changing from tundra to taiga and timber harvesting becomes possible, it does not directly indicate a decrease in agricultural production. In fact, the change might even open up new opportunities for agriculture or forestry, depending on the specific circumstances.
Therefore, the consequence applies only to Case 1.
