How do ecosystems typically respond to environmental changes?

• A. They become isolated without interaction between species
• B. They can adapt, migrate, or collapse based on resilience
• C. They remain unchanged regardless of the changes
• D. They always move to other regions to escape changes

Answer: (B)

Ecosystems are inherently dynamic systems that are influenced by various environmental factors such as climate change, habitat destruction, and resource availability. The correct answer highlights that ecosystems can manifest a range of responses to environmental changes due to their resilience. Resilience refers to an ecosystem's ability to withstand disturbances and then recover from them. When faced with changes, ecosystems may adapt by altering their structure or function to maintain stability. This adaptability might involve shifts in species composition, changes in nutrient cycling, or modifications in food webs. For example, certain species might thrive under new conditions, whereas others might decline; this illustrates a shift that still allows the ecosystem to function. Additionally, ecosystems may respond by migrating, where species might move to more favorable habitats in search of better conditions. This movement is particularly evident in the context of changing climates, where species may shift their ranges poleward or to higher altitudes. On the other hand, ecosystems can also collapse when they reach a tipping point, where the combined stressors exceed the system's capacity to absorb changes. Such a collapse often leads to significant alterations, and the ecosystem may not be able to recover to its original state. In contrast, the other options imply responses that are either static or overly simplistic. While some ecosystems might
