Document Summary
Element cycling is the transport & transformation of chemicals within an ecosystem. 4- input into the abiotic to the output of the biotic but they are linked via production and decomposition. Example would be acidic perciptiation as it penetrates through the soil. What is aquatic osteporis or jellification of lakes. -> softwater boreal lakes loss in calcium due to acid rain, logging and climate change example of linked due to chemical reactivity and material enrgy flow essential to the life of the daphnia. Materials move between ecosystem and may stick in a pool for a period of time and may change from one chem state to another. Physicalgradient move via the water or the soil. Chemical gradient would move and diffuse via the air like co2. Biological vectors will travel via salmon or larvae of insects. Sticking: residence time, and the represents the resistance of movement out of a place limited the losses of a system.
