Final answer:
The cycling of matter necessary for life is referred to as the biogeochemical cycle, which includes processes like the water cycle that are essential for life.
Step-by-step explanation:
The cycling of matter necessary for life is called the biogeochemical cycle. This term encompasses the continuous movement of water, carbon, nitrogen, and other essential elements through the biotic (living organisms) and abiotic components (non-living environment) of the Earth's ecosystems. One example of a biogeochemical cycle is the water cycle, which is crucial for sustaining life on our planet.
