A food chain in nature illustrates the flow of energy and nutrients between different organisms within an ecosystem. It shows the sequence of who eats whom in a specific habitat, starting with producers (plants) converting sunlight into energy through photosynthesis, then eaten by primary consumers (herbivores), which are then consumed by secondary consumers (carnivores), and so on. Ultimately, decomposers break down the remains of all organisms, returning nutrients to the soil for plants to use again. This interconnected system is vital for maintaining balance and sustaining life within ecosystems.
