Did you know?
- Its roots house bacteria that capture nitrogen from the air, so alder enriches poor, wet soil.
- Its wood lasts for ages under water, so it was used for piles and underwater foundations.
Could you guess it from clues?
WildGuessr picks a secret animal, plant, fungus, stone, prehistoric creature or space object and you ask yes-or-no questions about it, such as its group or where it grows. The fewer clues you need, the more points you score.
