grasshoppers from the first capture and grasshoppers that have not been captured yet.Write your data in Table 1.7.Release the grasshoppers back into the meadow.8.Complete calculations (on Table 2) based on your data collected and recorded on Table 1. 9.Complete Analysis Questions.
Table 1: Number of Grasshoppers collected during each captureTable 2: CalculationsAnalysis Questions:1.Conclude: What is the estimated population size of the grasshoppers living in this meadow? __________2.Apply: The population density of these grasshoppers is one indicator of whether or not they are considered as a pest and are capable of causing damage to crops and plant life. Normally, if these grasshoppers have a population density of 0-3 grasshoppers per square meter, they don’t pose a significant threat. Find the population density of these grasshoppers per square meter. If one acre is equal to 4,047 square meters, then on average, how many grasshoppers would be found in one square meter? 3.Evaluate: Based on the population density you determined, explain whether or not the grasshoppers pose a threat to nearby crops. 4.Identify causes: What are some factors that might cause changes in the population of grasshoppers?5.Analyze: What are some factors that might affect the accuracy of your estimate?6.Analyze: What are the advantages and disadvantages of the capture-mark-recapture method?
