Final answer:
In order for wildlife to do well, changes in their habitat must be suitable and gradual (Option D), as this allows species the necessary time to adapt and maintain ecosystem stability.
Step-by-step explanation:
The question pertains to how changes to habitat affect wildlife and what pattern these changes should follow to support wildlife sustainability. Considering the key role of habitat for both plants and animals, along with the impact of human-induced changes, it is evident that for a healthy habitat and in order to prevent the extinction of species, changes in the habitat must be suitable and gradual (Option D). Sudden and drastic changes can be harmful and even catastrophic to wildlife, resulting in the loss of biodiversity. Adaptations to new conditions take time, and gradual changes allow species to evolve or migrate if necessary. A stable and predictable environment offers the best chance for species to thrive and fulfill their ecological roles.
Suitable and gradual changes to the habitat allow species to adapt over time, which is necessary for sustainability in the ecosystem. In contrast, extreme and abrupt changes can lead to habitat destruction, making it difficult for species to survive and potentially leading to extinction. Therefore, maintaining stability and continuity in habitat changes is critical to life on Earth.
