What role do companion plants have in pest management?

Companion plants play an important role in pest management by attracting pests away from target plants. This is a beneficial strategy used in integrated pest management systems. Certain plants can lure pests that would otherwise harm the crops or target plants you want to protect. By drawing these pests to the companion plants, the damage to the primary crops is minimized, allowing them to thrive without as much interference from harmful insects.

The other options do not accurately represent the role of companion plants. They do not inhibit nutrients in nearby plants; rather, some companion plants can actually enhance the nutrient uptake of others. While they may reduce pest populations, they do not completely eliminate pests, as some insects may still be present in an ecosystem. Additionally, companion plants are not solely for aesthetic purposes; their primary purpose in this context is to support pest management and promote plant health through strategic planting.
