Some nematode worms suck plant juices from the roots of plants and are economically important agricultural pests. Some fungi are usually decomposers of plant material, but some trap and kill nematodes at times. Arthrobotrys traps and kills nematodes, especially when they lack nitrogen sources. These two facts suggest that farmers could find Arthrobotrys an important tool in combating nematode infestations. Which of the following research questions would make a good starting point for developing such a defense against plant-sucking nematodes?

Question

Quizplus · Accepted Answer

This research question directly addresses the potential for using Arthrobotrys as a tool for controlling nematode pests in agriculture. By understanding the relationship between nitrogen fertilization and the ability of Arthrobotrys to trap and kill nematodes, farmers can optimize their use of this fungus as a biological control method. Option B is not directly related to Arthrobotrys or its potential use as a biocontrol agent. Option C is interesting, but does not provide practical information for developing a defense against nematodes. Option D is also interesting, but does not provide information relevant to the potential use of Arthrobotrys in agriculture.
