Nata [24]

Answer:

increased risk of wildfires- both

local economy suffers- Case 1

carbon storage decreases - Case 2

agricultural production decreases - Case 1

carbon storage increases -  Case 1

disease vector range changes - Case 2

decreased water availability - Case 1

local economy thrives - Case 2

species range changes - Case 2

Explanation:

Fires are common to  taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.

On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.

Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.
