The consequence of food chain disruption in ecosystems can be severe, leading to trophic cascades that affect multiple species and ecological balance. When a species is removed or its population significantly altered, it can result in overpopulation of its prey or underpopulation of its predators, disrupting nutrient recycling and ecosystem functions. For example, the decline of a top predator might lead to the unchecked growth of herbivorous species, which can overconsume vegetation, resulting in habitat degradation. This disruption threatens overall biodiversity and ecosystem stability.
