Question

Main cause of extinction of species from tropical areas is

• A. Afforestation
• B. Deforestation
• C. Pollution
• D. Soil erosion

Answer 1

Answer: (B)

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, habitat loss, small population and position at a higher trophic level favor extinction. Since the species residing in the tropics have their major habitat in the form of forests, thus deforestation causes, extinction of such species.

So, the correct answer is 'Deforestation'.
