The degradation of food-falls at the bottom of the ocean can create partially chemosynthetic environments. In the case of sunken whale carcasses (whale falls), the supply of organic material supports an ecological succession of communities. But perhaps less well-documented than the scavengers at whale-falls are the creatures that rely on wood instead. When trees become uprooted by storms or ships capsize at sea, losing their buoyancy as the pressure of the ocean forces out any air trapped within, bits of wood sink to the ocean floor where they create fleeting oases of life (wood falls), including shipwrecks, like that of the Titanic. The scarcity of food in parts of the deep ocean creates an environment where very little goes to waste. The animal and microbial life that dwells down here has become resourceful, able to make the most of even unexpected resources. So it comes as no surprise that the deep ocean hosts complex biological communities adapted to thrive on this sunken wood.
