🔗 Interdependence — Why It Matters
In a stable community, all species depend on each other. If one species is removed, it creates a knock-on effect:
- If a predator disappears → prey population explodes → they eat all their food → they starve
- If pollinators disappear → plants can't reproduce → herbivores lose food → predators lose prey
- If decomposers disappear → dead material accumulates → nutrients locked up → plants can't grow
