The population dynamics are given from a 1 square meter quadrat sample for the years 2007-2011 (see above). Make a table like the one above and fill in the missing values. Graph a population curve for the invasive ant population (x-axis year; y-axis final population size at the end of each year) and for each of the following statements, indicate whether it is True or False. (Enter 1 for True and 2 for False) There is no problem with this invasion because ants could not cause any ecological damage in a woodlot. If this population does not reach carrying capacity, there will be over 1000 invasive ants in the 1m square quadrat in 2016 (10 years of population growth). The population of invasive ants is at carrying capacity in the woodlot ecosystem. The population of invasive ants is NOT at carrying capacity in the…arrow_forward
