Sunlight beams down on green plants, providing energy for photosynthesis, the process that lets plants make their own food. These plants, called producers, are eaten by animals, the consumers. Herbivores munch on leaves, and carnivores hunt these herbivores, transferring energy up the food chain. But energy decreases at each step! Finally, decomposers, like worms and fungi, break down fallen leaves and dead animals, returning nutrients to the soil. This cycle of nutrition and energy maintains the balance in our amazing ecosystem!
