  • The Friends of Nature youth club has been studying a local greenbelt area for several years. The plants and land shapes in the area have changed very little, except that a very strong wind about a year ago blew down nearly all the large dead trees. Some of the other things the club has learned are shown in the table. The club has decided to investigate the population changes shown in the table. To explain the decline in the squirrel population, they should first investigate

    dwindling food supply.
    increase in the duck population.
