In this business lesson, students learned about soil and its important characteristics. Soil, which is composed of tiny particles from rock, is essential for plant growth as it provides the necessary nutrients and water that roots absorb. The lesson emphasized that soil is a complex material containing both living (biotic) and non-living (abiotic) factors, such as bacteria and minerals, that contribute to a healthy environment for plants. Additionally, the presence of organisms like earthworms aids in soil aeration and nutrient distribution, enhancing overall plant health.
