- Q1The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which life-forms will help create the soil by breaking down bare rock?InsectsDeciduous treesLichensGrasses30sB.11.D: Ecological Succession
- Q2Which statement best describes the differences in species diversity between an ecosystem beginning the process of primary succession and one beginning the process of secondary succession?No differences in species diversity exist because both ecosystems initially lack living organismsSpecies diversity is much greater in the ecosystem undergoing primary succession because that ecosystem is experiencing a longer period with a lack of competition for spaceSpecies diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various speciesSpecies diversity is much greater in the ecosystem undergoing primary succession because the lack of soil provides a greater area for organisms to claim niches30sB.11.D: Ecological Succession
- Q3The graph below shows the changes in the number of species in an ecosystem. Which event was most likely the cause of the changes in species diversity in this ecosystem?A migration of locustsA small tornadoA large volcanic eruptionA flash flood30sB.11.D: Ecological Succession
- Q4Surtsey is an island located south of Iceland. The island was formed by a volcanic eruption and first appeared in 1963. The table below contains descriptions of changes in the population and diversity of species on Surtsey. Which of these lists the descriptions in the correct order of ecological succession on Surtsey?I, II, IV, IIIII, IV, I, IIIIV, III, I, IIIII, I, II, IV30sB.11.D: Ecological Succession
- Q5The graph shows the basic changes in a forest community after a disturbance occurred. The information shown in the graph suggests that the changes in the forest community were caused by —decreased species diversitytree-leaf replacement after a stormsuccession after a firerepeated habitat destruction30sB.11.D: Ecological Succession
