question 10 of 25
why is planting a variety of crops on one farm more sustainable than monoculture?
a. it increases parasite infection.
b. it increases farming efficiency.
c. it increases biodiversity.
d. it increases farm profits.

Explanation:

Planting a variety of crops (polyculture) instead of a single - crop (monoculture) promotes biodiversity. Different crops support various organisms, including beneficial insects, soil microbes etc. This biodiversity helps in maintaining a healthy ecosystem on the farm, which is a key aspect of sustainability. Options A is incorrect as it should decrease parasite infection in some cases due to dilution effect. Option B is not the main reason related to sustainability in this context. Option D is not the most fundamental reason compared to biodiversity for long - term sustainability.

Answer:

C. It increases biodiversity
