Which of the following is a disadvantage of monoculture?

Monoculture, the agricultural practice of growing a single crop species over a wide area for consecutive seasons, presents several disadvantages, one of which is the increased vulnerability to pests. When a single crop is planted extensively, it creates an environment where pests can thrive because they have a consistent food source. This lack of biodiversity means that pests can rapidly multiply and potentially devastate the crop, as there are no competing plants to help mitigate their effects.

In contrast to practices that promote biodiversity, such as crop rotation or intercropping, monoculture lacks the natural checks and balances that diverse ecosystems provide. This reliance on a single crop not only makes farmers heavily dependent on chemical pest control methods but also risks significant yields if a pest outbreak occurs, as all plants would be affected uniformly.

Increased biodiversity, stabilized crop production, and improved marketability do not align with the downsides of monoculture. In fact, these aspects are often associated with polyculture systems, which can provide resilience against pests and environmental changes, leading to more sustainable agricultural practices.
