Age range 8 to 12 This is a story about trees and fungi connected through a 'wood wide web' — told by one tiny fungal spore. A little fungus meets a baby cacao tree and they learn to feed each other. They cooperate with a forest of plants and a metropolis of microbes in the soil. But when drought strikes can they work together to survive? The fourth book in the Small Friends Books series, this science-adventure story explores the Earth-shaping partnerships between plants, fungi and bacteria. Part of the Small Friends Books series – Stories of Partnership and Cooperation in Nature.
