Final answer:
An elemental cycle is the movement of elements through different biogeochemical cycles in ecosystems.
Step-by-step explanation:
An elemental cycle, in the context of biology, refers to the continuous movement and exchange of elements through various biogeochemical cycles in ecosystems.
These cycles involve the cycling of elements such as carbon, nitrogen, phosphorus, and oxygen between living organisms, the atmosphere, water bodies, and the Earth's soil.
For example, the carbon cycle involves processes like photosynthesis, respiration, decomposition, and fossil fuel combustion, which contribute to the movement of carbon between different reservoirs in the environment.
