The answer is - because over 90% of this biome has been converted to agriculture.

This biome has been much larger before the development of the agriculture in this part of the USA, but because this biome provided large territories with deep fertile soil and predominantly lowland areas, people started using it for agriculture because it was the most suitable for that. So little by little, the biome was declining and more and more of it was becoming agricultural land.

Earl Sutherland won the Nobel prize for discovering how epinephrine stimulates the breakdown of glycogen, a molecule that belong
Levart [38]

Answer:

There was no receptor for epinephrine to associate with and invigorate the sign transduction course that prompts the actuation of the compound  

By and large, Earl Sutherland helped in translating and discovering the breakdown of the glycogen into glucose-1-phosphate in nearness of glycogen phosphorylase and this sign course pathway is activated by the epinephrine. The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.
