Nutrient Cycle Optimization in Forest Ecosystems: A forest with trees and grass in the background, featuring a cross-section of soil in the foreground. The soil is divided into two layers: the top layer shows roots and plants growing, while the bottom layer reveals a network of microscopic organisms and nutrients being exchanged between them. A white line connects these two layers, symbolizing the flow of nutrients from the soil to the plants above. This image effectively illustrates the nutrient cycle optimization process, where microorganisms in the soil break down organic matter into simpler compounds that can be absorbed by plant roots.
