Describe the biodiversity level that is most obvious in each image. Fig. 5.1, Fig. 5.2, Fig. 5.3.
Outline how the students could measure the biodiversity of plants and insects along a prairie strip.
Mathematical methods and statistical tests are useful for summarising and comparing biodiversity data. Name the mathematical method or statistical test that the students can use: to estimate the total biodiversity of a prairie strip; to test whether plant biodiversity is associated with insect biodiversity.
Prairie strips have both environmental and economic impacts. Scientists have taken long-term measurements of the environmental impacts of prairie strips. The scientists discovered that when prairie strips made up $10\%$ of a crop-field: soil erosion was reduced by $95\%$; mineral loss from the field was reduced by $90\%$ for phosphorus compounds; mineral loss from the field was reduced by $85\%$ for nitrogen compounds. Crop plants need phosphorus (P) and nitrogen (N) to grow. Evaluate the economic effects of prairie strips on farming.
