Quizplus · Accepted Answer

A biogeochemical cycle refers to the transitioning and residence of specific chemicals, such as carbon, nitrogen, and phosphorus, among living and nonliving systems. This includes the processes of uptake by organisms, release by decomposition, and exchange with the atmosphere, water, and soil. The movement of biogeochemical minerals through the rock cycle (A) and exchange of chemicals among magmatic and solid-phase systems (B) are not part of the biogeochemical cycle, as they do not involve interactions with living organisms.
