question 27 of 30
which of the following is a disadvantage of planting a variety of crops rather than a monoculture?
a. it can decrease farming efficiency and profit.
b. it is more likely to lead to crop failure.
c. it can promote biodiversity in ecosystems.
d. it can lead to an increased risk of parasite infection.

Explanation:

Planting a variety of crops can be more complex to manage than monoculture. Different crops have different needs in terms of water, nutrients, and pest - control. This complexity can reduce farming efficiency and potentially lower profit margins due to increased management costs. Option B is incorrect as diverse crops can actually buffer against crop failure. Option C is an advantage, not a disadvantage. Option D is incorrect as mixed - cropping can sometimes reduce pest and parasite problems.

Answer:

A. It can decrease farming efficiency and profit.
