Abstract
Decomposition is a crucial process in nutrient cycling, where dead organic matter turns into nutrients for the environment. Height is a significant abiotic factor that can influence these factors. Dried primrose was chosen for this experiment to test how much height affects decomposition; 8 mesh bags were filled with 4.0g of dried primrose leaves. Four bags were placed at ground level, and four were placed on top of a plant, 2ft above the ground. Using the fishing line, the bags at each site were tied together to prevent them from blowing away. By changing the height of the plants, the organisms able to reach the leaf litter are altered, which can cause variations in the rate of decomposition. Light is also a significant abiotic factor that affects the rate of decomposition, so the difference in total light reaching the leaf litter on ground level and above ground can alter decomposition as well. The litterbags located on ground level underwent a higher level of decomposition and decreased the most in biomass. The higher level of decomposition at ground level suggests a more advantageous nutrient cycling when leaf litter is closer to the ground. This study provides valuable insight into the effect of height on the ability of leaf litter to undergo decomposition and aid in nutrient cycling.
