Answer:
The correct answer is temperate grassland to coniferous forest.
Explanation:
While driving through the great plains of Nebraska to Northern Idaho, one travels through two biomes, that is, from temperate grassland to coniferous forest.
Temperate grasslands refer to the regions of open grassy plains, which are sporadically populated with trees. The temperate grasslands can be witnessed in different regions of south and north of the equator comprising Australia, Central North America, and Argentina.
While coniferous forests comprise vegetation mainly of cone-bearing scale-leaved or needle-leaved evergreen trees known as conifers, found in the regions, which exhibit long winters and moderate to high annual rainfall.
