Garlic mustard is an invasive plant species in North American temperate forests. Garlic mustard secretes an allelochemical that interferes with relationships between native tree roots and their mycorrhizal fungi. This would be an example of
A. interference competition.
B. exploitative competition.
A. interference competition.
The garlic mustard is releasing a chemical compound that disrupts the mutualistic relationship between native trees and mycorrhizal fungi. This would interfere with the trees' ability to uptake phosphorus. This is an example of interference competition.
