190SpeakingTask 4Question 4 of 6The professor explains cyclic disturbance by giving someexamples. Explain how the examples demonstrate it.Preparation time : 30 secondsResponse time : 60 secondsTrack_28Reading Time: 45 secondsCyclic DisturbancesEvery ecosystem in the world is subject to environmental disturbance,which is defined as a temporary change in normal environmentalconditions that leads to a significant change in an ecosystem. Thesedisturbances are typically divided into two kinds: natural disturbances andanthropogenic, or manmade, disturbances. Human-caused disturbancesinclude mining, forest clearing and the introduction of invasive species.Natural disturbances may be relatively minor ones like flooding, fires andinsect outbreaks, or major ones like earthquakes and volcanic eruptions.On the other hand, natural disturbances often result in cyclical changes,in which the ecosystem eventually returns to the previous state and thenrepeats the process.Track_29
