### The Fungal Web: Nature’s Underground Network
Beneath the quiet floor of a forest lies a complex, living network that rivals the human internet. Known to scientists as the mycorrhizal network, this underground system consists of millions of microscopic fungal threads called hyphae. These threads intertwine with the root systems of trees and plants, creating a vast biological web. Through this network, trees exchange vital nutrients such as carbon, nitrogen, and phosphorus. Larger, older trees—often referred to as 'mother trees'—use this fungal network to send sugars and nutrients to younger saplings struggling to grow in the shade.

- BTrees in a forest compete aggressively with one another for available sunlight.
- CFungal threads called hyphae are harmful parasites that destroy healthy forest ecosystems.
- DThe human internet was modeled directly after forest root systems in the 1990s.
