The correct answer is - biomass from the decomposing grasses.
The Midwest is a region known for its highly fertile soil. The reason for this is that the weathered bedrock combines with huge amounts of biomass. The biomass is almost entirely form the grasses. The grasses grow naturally in this region and they dominate the landscape. They grow and die out relatively quickly, as most of those grasses are one season grasses. They manage to create very large amounts of biomass every year, and also they decompose very quickly. The grasses also are high in nutrients, so once decomposed, they give the soil a lot of nutrients as well, which makes it very fertile and suitable for agriculture.
Answer:
The statement is true. Las Vegas, Nevada, has seen a great increase in the demand for water since it is one of the fastest growing regions in the U.S.
Explanation:
Las Vegas is the most populous and most densely populated city in the state of Nevada. It is located in the south of the state, in Clark County.
According to the 2010 national census, the city itself has 583,756 inhabitants, and its metropolitan region has about 1.9 million inhabitants. It is the 30th most populous city in the United States and is considered to be the fastest growing city in all of North America.
Population growth was especially marked in the 1990s, when the population went from a little over 200,000 people to more than 500,000. This brought a consequent lack of resources due to the desert location of the city, which was solved only with investment in infrastructure by the state government.
