One example of a factor that affects an ecosystem's biodiversity is habitat destruction. This factor has a negative impact on the entire ecosystem, from individual populations to the community level. When natural habitats are destroyed or altered, the species that rely on that habitat for food, shelter, and reproduction are directly impacted. This can lead to a decrease in population size or even local extinction of certain species within the ecosystem. Additionally, habitat destruction can also indirectly affect other species within the ecosystem through disruption of food webs and ecological relationships. Overall, habitat destruction is a major threat to global biodiversity and requires conservation efforts to mitigate its impacts.
