How does the food chain keep balance in nature?

The food chain maintains balance in nature by regulating populations of different organisms and ensuring energy flow through ecosystems. Producers, such as plants, convert sunlight into energy, forming the base of the chain. Herbivores consume these producers, while carnivores prey on herbivores, creating a cycle of energy transfer. This interplay helps prevent any one species from overpopulating, thus maintaining ecological stability and promoting biodiversity.
