The pathways that macronutrients and micronutrients follow through ecosystems are what?

The pathways that macronutrients and micronutrients follow through ecosystems are known as biogeochemical cycles. These cycles involve the movement of nutrients through different components of the ecosystem, including the atmosphere, hydrosphere, lithosphere, and biOSphere. Macronutrients like nitrogen, phosphorus, and potassium are cycled through processes such as decomposition, mineralization, and uptake by plants, while micronutrients are often involved in more specialized biochemical processes. Together, these cycles ensure the availability of essential nutrients for all living organisms, maintaining ecosystem health and productivity.
