Clemson's onside kick went out of bounds. Coker took a knee and after a two-year drought that felt like eternity in Tuscaloosa, Alabama was back on top. The Crimson Tide became the second team in college football's poll era, dating back to 1936, to win four titles in seven seasons.
The Problem With Monocultures The problem with monocultures, Wetzel said, is that if an insect likes the crop, that insect has a large food supply to draw from all in one place. Conversely, a field containing a variety of plants does not offer a large block of food for the insect, so it will not get the nutrients it needs to survive and thrive.
Examples of monoculture include lawns and most field cs wheat or corn. The term is also used where a single species of farm animal is raised in large-scale concentrated animal feeding operations (CAFOs).xamples include wheat fields or apple orchards or grape vineyards. Because each species has the same growing requirements and habits, planting, maintenance (including pest control), and harvesting can be standardized, resulting in greater yields.
