Chapter 5: Interplant Interference and Competition

5.3 Resource Competition

The first main concept Vince addresses is the effect of weeds on crops, as illustrated in this graph he shared.  Based on the graph, what typically happens to crop yield as the number of weed plants in a field increase? He describes the different factors or resources that crop and weed plants compete for which influence this.

Make sure you can answer the following application questions based on what he described.
