Flowering rush (Butomus umbellatus) is a pink flowering perennial that has been identified as a prohibited noxious weed in Alberta. It is native to Europe, Africa, and Asia, but due to its prolific growth rate on shorelines, it has been crowding out the native species of Alberta. The following table shows the population growth of flowering rush in Chestermere Lake of Calgary. Year Population (N) 2007 10 2008 7 2009 8 2010 22 2011 46 2012 77 2013 158 2014 319 2015 297 2016 355 2017 334 2018 313 2019 291 a) What is the growth pattern of flowering rush in Chestermere Lake? a. lag b. J-curve c. exponential d. logistic   b) What is the carrying capacity of the flowering rush population? a. approximately 285 plants b. between 291 and 355 plants c. approximately 400 plants d. between 158 and 355 plants
