Question

What is the major cause of the extinction of many species of organisms?

• A. Less availability of food
• B. Air pollution
• C. Using fossil fuels
• D. Habitat degradation

Answer 1

The correct option is D

Habitat degradation

Habitat degradation or destruction is the single most important threat to wildlife in the modern age we live and the primary cause of species extinction worldwide. When a habitat is destroyed, the plants, animals and other organisms that occupy the habitat have reduced their carrying capacity or ability to survive, to the point that populations decline and become extinct. Many species have specific requirements for food and shelter for their survival that can only be found in certain ecosystems, which if not provided will result in extinction.
