Where might this type of ecosystem be located? Give one specific example.Describe the structure of the ecosystem: List both the abiotic components and biotic componentsDescribe the function of the ecosystem: How do the abiotic and biotic components interact in biogeochemical cycles? Describe both the carbon and nitrogen cyclesDescribe disturbance and recovery: Describe one natural and one human caused disturbance to the ecosystem you have chosen. Explain the damage to the ecosystem, including how the abiotic and biotic characteristics of the ecosystem changed.Explain how ecosystems recover naturally based on resilience mechanisms and the theory of secondary succession.
