Imagine an isolated ecosystem where all primary producers suddenly die. Explain the cascading effects on the ecosystem's structure and the adaptations of the few surviving organisms after 20 years.

The ecosystem collapses. Herbivores die off, leading to carnivores also struggling. Scavengers may temporarily flourish. Survivors adapt by becoming extremely efficient at finding scarce food sources, or by altering their diets to consume previously unpalatable materials. High competition arises.
