Answer: True</h3>
Healthy top soil is needed to grow crops, which in turn some of it becomes food. Erosion is the process in which top soil is carried away by the wind or rain water (depositing it into nearby lakes or streams). Without this top soil, farming becomes more difficult and crop yields likely decrease. In some cases, no crops can be grown at all. An extreme example of soil erosion, specifically wind-driven soil erosion, is the 1930s dust bowl during the Great Depression. This occurred due to over-farming and it led to massive dust storms. In turn, it caused many farmers to leave the area.
Eubacteria can obtain foods in a bunch of different ways. The earliest bacteria were likely lithotrophs which use inorganic compounds (compounds that don't have carbon) along with CO2 to make food. There are also photosynthetic bacteria which use the sun's light to use CO2 from the environment to make food
