In an ecosystem How can positive feedback destabilize an ecosystem?

Positive feedback in an ecosystem can destabilize it by amplifying changes that lead to rapid shifts in conditions. For example, if a rise in temperature causes ice to melt, the reduction in reflective surfaces leads to further warming, which can accelerate melting even more. This self-reinforcing cycle can push the ecosystem beyond its natural resilience, potentially resulting in habitat loss, species extinction, or the collapse of ecological balance. Ultimately, such destabilization can disrupt food webs and nutrient cycles, threatening the overall health of the ecosystem.
