Every ecosystem is a dynamic system,how?

 

• An ecosystem is a community of living organisms which exist along with the nonliving components of their environment, interacting as a system.
• These biotic and abiotic components are linked together through nutrient cycles and energy flows.
• As ecosystems are defined by the network of interactions among organisms, or between organisms and their environment, they can be of any size, but usually encompass specific, limited spaces.
• Ecosystems are dynamic entities controlled both by external and internal factors. External factors, such as climate and the parent material that forms the soil, control the overall structure of an ecosystem.
• While the resource inputs are generally controlled by external processes, the availability of these resources within the ecosystem is controlled by internal factors such as decomposition, root competition, or shading.
• From one year to another, ecosystems experience variation in their biotic and abiotic environments. Animal populations vary from year to year, building up during resource-rich periods, but crashing as the food supply becomes scarce.
• Thus, ecosystem is a dynamic system.
