Nutrient cycles keep essential ______ available to plants and other living organisms. The _____ of these elements is critical to maintaining life on Earth. The carbon cycle, the nitrogen and water cycle all have important ____-. The _________ cycle lacks a true phosphorus phase, and is slow and depends on the water cycle, also called the hydrologic cycle.

Answer 1

Nutrient cycles, also known as biogeochemical cycles, describe the movement of chemical elements through different sources and processes, such as the atmosphere, soil, rocks, bodies of water, and organisms. Nutrient cycles keep essential nutrients available to plants and other living organisms. The cycling of these elements is critical to maintaining life on Earth. The carbon cycle, the nitrogen cycle, and the water cycle all have important roles. The phosphorus cycle lacks a true phosphorus phase and is slow, depending on the water cycle, also called the hydrologic cycle.
