Which type of environmental change is the most difficult for an organism to adjective to?

Rapid climate change is often the most difficult environmental change for organisms to adapt to. This is due to the speed at which temperatures shift, habitats change, and food sources fluctuate, leaving little time for evolutionary adaptations to occur. Additionally, the complexity of interconnected ecosystems can result in cascading effects that further challenge an organism's survival. In contrast, gradual changes may allow for more time and opportunities for adaptation.
