Answer:
B) Absence of native grasses
Explanation:
The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.
Explanation:
Biome and the ecosystem are the words that are sometimes applied interchangeably to explain a particular kind of environment.
The biome represents the geographical region that has the same kind of ecological atmosphere, climate and mostly consistent collection of the species and it is made of a large number of ecosystems.
An ecosystem represents a particular element of the biome and a species that nearly interact in it.
Thus the biome is the collection of various types of ecosystems.
Tropical rainforest is a biome which is warm and wet, with little seasonal variation in temperature and frequent precipitation.
<h3>What is a Biome?</h3>
This is referred to an environment which has features such as being greatly influenced by abiotic factors such as sunlight, water etc.
Tropical rainforest as the name implies has a large and frequent amount of precipitation thereby making it wet with little seasonal variation in temperature. It is also characterized by large trees which form canopies in the region.

Monomers are molecules whose linkage between them form polymers.
<h3>What are monomers?</h3>
Monomers are molecules that have a low molecular mass.
<h3>Characteristics of monomers</h3>
- When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.
- Natural monomers allow the formation of biomolecules found in living beings.
- Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).
Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
