Ecological systemsundergoperiodic disturbancesdue to natural processes, biological interactions, human activities, succession, and the resilience and adaptation of species.Ecological systems often undergo periodic disturbances. These disturbances refer to events or changes that disrupt the normal functioning of anecosystem. There are several reasons why ecological systems experience these disturbances.1. Natural processes: Natural events such as storms, floods, fires, and volcanic eruptions can cause disturbances in ecosystems. For example, a forest fire can lead to the destruction of trees andvegetation, altering the composition and structure of the ecosystem.2. Biological interactions: Interactions between different species can also cause disturbances. For instance, predator-prey relationships can influence population dynamics and lead to fluctuations in ecosystem structure.3. Human activities: Human activities likedeforestation, pollution, and habitat destruction can significantly disrupt ecological systems. These disturbances often have negative impacts on biodiversity and ecosystem services.4. Succession: Ecological succession refers to the process by which ecosystems change over time. Disturbances can play a crucial role in initiating succession and shaping the structure of ecosystems. For example, after a fire, pioneer species may colonize the area and pave the way for other species to establish.5. Resilience and adaptation: Ecological systems have the ability to recover from disturbances and return to their original state. This resilience is important for maintaining ecosystem stability and functionality. Some species may even adapt to disturbances by developing specific traits or behaviors that allow them to thrive in these changing conditions.Know more aboutdeforestationhere:brainly.com/question/32556346#SPJ11(Complete question)ecological systems often undergo periodic disturbances.
