💡 What Are Surface Exchanges?
Surface exchanges occur whenever materials, energy, or substances move across a boundary or interface between two environments. These exchanges are fundamental to countless natural processes, including gas exchange in living organisms, nutrient transfer, heat transfer, water movement, and ecosystem interactions.
By exploring surface exchanges, students gain a deeper understanding of how organisms survive, how ecosystems function, and how physical systems maintain balance. This topic provides an excellent bridge between biology, environmental science, and physical science concepts.
