Why do arrows flow from producer to consumer in a good chain?

In a food chain, arrows flow from producers to consumers to represent the direction of energy and nutrient transfer. Producers, like plants, convert sunlight into energy through photosynthesis, creating organic matter. Consumers, such as herbivores and carnivores, rely on these producers for energy. The arrows symbolize this flow of energy from one trophic level to the next, illustrating the interconnectedness of ecosystems.
