How might habitat destruction impact biodiversity in an ecosystem?

• A. Increases species diversity in most cases.
• B. Has no effect on biodiversity.
• C. Improves soil fertility but harms biodiversity.
• D. Reduces species diversity, disrupts food webs, and can lead to ecosystem instability.

Answer: (D)

Habitats provide the space and resources organisms need to live, feed, reproduce, and interact. When habitat destruction occurs, those places disappear or shrink, causing many species to lose critical resources and populations to decline or go extinct. This lowers the number of species in the area, reducing biodiversity. With fewer species, the food web becomes disrupted: predators lose prey, prey may become overabundant or vanish, and important interactions like pollination and decomposition weaken. The ecosystem’s energy flow and nutrient cycling become less efficient, making it less stable and less able to recover from disturbances. Fragmentation worsens this by creating small, isolated populations that are more vulnerable to genetic problems and local extinction, hindering recolonization after losses. So, habitat destruction reduces species diversity, disrupts food webs, and can lead to ecosystem instability.
