Describe three factors that make up the abiotic environment of a tropical rainforest

Abiotic factors are the things that affect the trees and animals that lived in a tropical rainforest. The first factor is poor nutrient content in soil. The soil is typically poor in a tropical rainforest due to the heavy rainfall that washes away nutrients and makes the soil usually acidic which some plants cannot tolerate. The second factor is sunlight, the amount of sunlight is limited at ground level primarily due to heavy overhead tree canopy, the forest floor may just receive as little as 2 percent of the sunlight. Moreover, the third cause for abiotic environment is environmental changes like drought. The occurrence of El Nino is a result of climate change that caused limited water resources in the tropical rainforest.
