Brazil Nut Tree

Brazil nut trees cannot reproduce without specific partners at multiple life stages. Their flowers can only be opened by large-bodied orchid bees strong enough to lift the coiled hood. Their hard, coconut-sized fruits can only be opened by agoutis - large rodents with strong teeth who cache nuts, some of which germinate. Remove either partner and the brazil nut can't complete its life cycle.

This multilayer dependence explains why brazil nuts resist domestication. Commercial plantations never achieved viable yields because they lacked the rainforest ecosystem - the orchid bee habitat, the agouti population, the forest structure that supports both. You can plant brazil nut trees, but you can't plant the partnership. All commercial brazil nuts still come from wild harvest.

The tree's strategy makes sense in its native context. In the Amazon rainforest, orchid bees and agoutis are reliably present. The partnerships evolved over millions of years in a stable ecosystem. The vulnerability only becomes apparent when you try to extract the tree from its network. The brazil nut is less an organism than a node in a system.

The business insight is that some products can only exist within specific ecosystems. Brazil nut teaches that apparent independence can mask deep dependencies. Companies that seem like standalone businesses might actually be nodes in industry ecosystems - viable only because of regulatory structures, supply chains, customer expectations, or complementary products that can't be replicated in isolation.
