11. The micro-organisms restore the soil s natural nutrient cycle and build soil organic matter. 12. This is very important in ecosystems, for the nutrient cycle . 13. Feeding activities of invertebrates on the sediment surface and plant matter promotes nutrient cycling . 14. Microalgae play a major role in nutrient cycling and fixing inorganic carbon into organic molecules. 15. These physical changes will impact nutrient cycling and biological processes within the basin as well. 16. Nutrient cycles are developed between fish, plant & soil.17. In some cases, ecosystem productivity may be increased due to grazing effects on nutrient cycling . 18. Thus fungi are engineers controlling nutrient cycles in ecosystems. 19. It performs essential nutrient cycling functions in forests. 20. Several nutrient cycles are important in the aquarium.
