What Are Some of the Abiotic Factors in a Tropical Rainforest?

Some of the abiotic factors found in a tropical rainforest are high temperatures, heavy rainfall, poor nutrient content in soil and sunlight that is found primarily at the tree canopy level while remaining limited at ground level. Because of the heavy overhead canopy, the forest floor may receive as little as 2 percent of the sunlight. Precipitation, which is a significant abiotic factor in a non-aquatic ecosystem, can range between 98 and 177 inches annually in a tropical rainforest.
