The process in which energy is transferred from one organism to another is known as energy flow. This typically occurs through trophic levels, where energy is passed from producers (such as plants) to consumers (like herbivores and carnivores). Energy transfer is often depicted in a food chain or food web, illustrating the complex interactions between different organisms. Each level in this hierarchy reflects a loss of energy, primarily due to metabolic processes, making energy flow crucial for understanding ecosystem dynamics.
