Pioneer plants are depicted in Figure 2. pa href=”http://shawmst.org/biology/files/2012/04/clip_image004.gif”img style=”border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px” title=”clip_image004″ border=”0″ alt=”clip_image004″ src=”http://shawmst.org/biology/files/2012/04/clip_image004_thumb.gif” width=”502″ height=”207″/a pbLadder Question C/b pIt’s important to be able to read data represented in more complicated ways. Identify the five pieces of information represented in figure 2. Which are independent variables and which are dependent variables? pThe final stage of ecological succession is characterized by the presence of the climax community, the oak-hickory forest. Figure 3 depicts the gradual change from pine to hardwoods. pa href=”http://shawmst.org/biology/files/2012/04/clip_image005.gif”img style=”border-bottom: 0px; border-left: 0px; display: inline; border-top: 0px; border-right: 0px” title=”clip_image005″ border=”0″ alt=”clip_image005″ src=”http://shawmst.org/biology/files/2012/04/clip_image005_thumb.gif” width=”466″ height=”312″/a pbLadder Question A/b pAt about what year does the amount of hardwoods outnumber the amount of pines? pFollowing are some act sample questions on the above passage: ol liOn the basis of the data presented in Figure 1, approximately 80 years after the abandonment of cropland, the land would contain: ol lipine seedlings only. lioak-hickory hardwood forests only. liearly invading species like horseweed, aster, and broomsedge. lilarge pine trees with an understory of hardwood trees./li/ol liAccording to the information in Figure 3, a 150-year-old climax community would contain oak and hickory trees with a density of approximately: ol li3,000 trees per unit area. li5,000 trees per unit area. li15,000 trees per unit area. li20,000 trees per unit area./li/ol liOn the basis of the data depicting the gradual change from pine forest to an oak-hickory forest, after 100 years, as the density of the pine trees: ol liincreases, the density of the oak-hickory trees increases. liincreases, the density of the oak-hickory trees decreases. lidecreases, the density of the oak-hickory trees increases. lidecreases, the density of the oak-hickory trees decreases./li/ol liGiven the information in Figure 1, which of the following conclusions concerning ecological succession in an abandoned cornfield is most correct? ol liSuccession in an abandoned cornfield begins on bare rock. liSuccession is characterized by the replacement of one plant community by another until a climax community has been achieved. liThe height of the plants in the communities decreases as succession progresses to the climax stage. liThe plant species change continuously during succession, but the change is more rapid in the later stages than in the earlier stages./li/ol liAccording to Figure 2, pioneer plant(s) showing a progressive increase in summed diameter of stems per unit area over the course of several years of succession is(are): ol lihorseweed only. libroomsedge only. liaster and broomsedge only. lihorseweed, aster, and broomsedge./li/ol/li/ol
