You were driving through the great plains of nebraska to northern idaho. gradually, the grassland gave way to tall conifers. which of these biomes did you travel through?

a.) emperate grassland to coniferous forest.
b.) savannah to coniferous forest.
c.) prairie to temperate forest.
d.) savannah to temperate forest.

Option (A)

Explanation:

The great plains of Nebraska are comprised of the temperate type of grassland biome where there is abundant species of grass, that comprises the flowering plants, along with some wild herbs. Prairies and Steppes are the main sub-division of this type of biome, where the Prairies are characterized by the presence of tall grasses and Steppes are characterized by the presence of shorter grasses.

On the other hand, the great plains of Northern Idaho is comprised of Coniferous forest biome, which generally occurs in the latitude between 50° to 60°N. This biome consists of trees that grow needles and fewer tree leaves and there is an absence of flowers. These plant and tree species can successfully grow in the region which is very cold or dry in nature. Some examples of conifers include spruces, firs, and pines.

Thus, as one travels from the great plains of Nebraska to Northern Idaho, it means that the person is traveling from temperate grassland to a coniferous forest.

Hence, the correct answer is option (A).
