Amy is experimenting to see how a truss (a type of support) can strengthen a bridge. Amy builds several models of bridges out of
toothpicks. Each model has a different number of trusses. Amy suspends each model between two desks. She then adds lead weights to each bridge, one-by-one, until the bridge breaks. In the chart below, Amy recorded how many lead weights each bridge held before breaking.
What happens to the population density and competition if the birth rate decreases? The birth rate would increase is the population density competition increased. Hope I helped.
