Popular UyMICS & Ecosystom Change A certain population of beavers builds dams across a stream to catch fish. Some years the stream carries more water than other years. The data below was collected by scientists studying the stream over a sixteen year period. Average Stream Depth Average Number of Average Number of (meters) Beaver Dams Beavers Years 2000-2003 2004-2007 1.20 17 0.92 2008-2011 1.45 2012-2015 0.78 If the average depth of the stream for the next 4 years is 1.60 meters, which of the following is most likely to occur? OA The average size of each beaver will increase OB. The size of the beaver population will decrease OC. The size of the beaver population will increase OD. The average size of a beaver dam will decrease

Answer 1

Option C, The size of Beaver population will increase.

As per the data provided in the table, we can see there is direct correlation between the no. Of Beaver dams, Beaver Population and the Depth of the Stream. As the stream gets deeper, the population of of beavers increase. When stream depth is less, Beaver population also declines. So assuming the same trend, if the stream depth for next 4 years, increases to 1.60 meters, the beaver population will increase.
