How could cutting down a forest case a change in biodiversity?

Cutting down a forest significantly impacts biodiversity by removing many plant and animal species. Forests are complex ecosystems that provide habitat, food, and shelter to a wide array of species. When a forest is destroyed, the organisms that depend on that habitat are often displaced or lose their lives, leading to a decline in species populations and a reduction in overall biodiversity. The removal of mature trees, for instance, can disrupt the life cycles of various organisms that rely on those trees for survival—such as birds, insects, and mammals—causing cascading effects throughout the ecosystem.

Additionally, the loss of plant species means that the food and shelter necessary for herbivores and the predators that rely on them are diminished, further threatening species survival. Therefore, the consequences of deforestation are profound, leading to a decline in the variety and richness of life forms in the affected area. The correct choice reflects this reality, highlighting the negative impact of habitat loss on biodiversity.
