The biogeochemical cycles that supply elements essential for building organic molecules are: Phosphorus cycle, Carbon cycle, Nitrogen cycle.

Explanation:
These cycles are essential because they provide key elements that are fundamental components of organic molecules:
Carbon cycle: Carbon is the backbone of all living things because it can build stable, versatile, and complex molecular structures that are the foundation of life. (e.g., carbohydrates, lipids, proteins, nucleic acids).

Nitrogen cycle: Nitrogen is essential for amino acids (proteins) and nucleotides (DNA, RNA). Also nitrogen is a crucial part of proteins...
