What biological concept applies to growth disturbances in monocultures?

• A. Genetic diversity
• B. Inbreeding
• C. Pest vulnerability
• D. Competitive advantage

Answer: (C)

The concept of pest vulnerability is particularly relevant when discussing growth disturbances in monocultures. Monoculture refers to the agricultural or forestry practice of growing a single species, variety, or strain over a large area. While this approach can provide benefits such as increased yield and simplified management, it also leads to significant risks, particularly regarding pest and disease outbreaks. In monocultures, the lack of genetic diversity means that all the plants are genetically similar, which makes them equally susceptible to the same pests and diseases. If a particular pest targets that specific species or strain, it can decimate the entire crop or plantation because there are no alternative varieties present that may have evolved resistance. As a result, significant growth disturbances occur when these pests take hold, leading to reduced productivity and potential loss of the entire crop. This heightened level of vulnerability demonstrates the importance of genetic diversity and mixed planting strategies in reducing the overall risk of pest outbreaks.While the other concepts may relate to certain aspects of plant growth and ecology, they do not directly address the increased susceptibility to pests inherent in monocultures.
