Monocropping is the practice of growing only one type of agricultural crop in a large area. Farmers engaging in the practice often use specialized farming equipment, which is cheaper than human labor. Monocropping reduces the genetic diversity of crops, which makes them more susceptible to which of these?

Monocropping is the practice of growing only one type of agricultural crop in a large area.

Explanation:

*Monocroppong is the practice of growing only one type of agricultural crop in a large area of land*. *For example, the growing of only Cotton on a farmland*. Crops here are not mixed with other diverse crops,hence the name; Monocropping... ..A major advantage of Monocropping is that,*it is cheaper than mixed farming*.

Reduction in genetic diversity in monoculture plants  reduces  resistance  to diseases, infection and pest  , therefore makes these plants   more susceptible to diseases and pests attacks., thus  low products yields and sustainability.

. Thus because of absence of genetic diversity as a result of cultivating the same type of crops, year in-year out, on the same piece of land, there is little chances of variation, which reduces diversity among the plants.Therefore if there is an outbreak of a particular diseases in the plant population,which  starts with a plant,assuming that the other plants were genetically different from the infected plants,they would developed resistance,and therefore  be able to resist and escape the diseases effects.However since they all have virtually similar genetic traits due to low diversity, the diseases will affects them all, with the likelihood of wiping out the entire population.

Thus sustainability  and product yield is also affected.

Explanation:

the answer is b. 0; 4

it would lead to upper respiratory infections and pneumonia.
