In a forest reserve where top predators (wolves and cougars) were removed, the deer population grew rapidly. After 6 years, wildflower species and young tree saplings disappeared due to overgrazing. What principle does this demonstrate?

Herbivores improve wildflower diversity by consuming leaves. Removing top predators leads to herbivore overpopulation, causing overconsumption of plant producers and ecosystem imbalance. Wildflowers require high deer populations to grow. Predators reduce plant biomass.

Removing top predators leads to herbivore overpopulation, causing overconsumption of plant producers and ecosystem imbalance.
