Which of the following can be threats to the biodiversity of a geographical area?

  1. 1.Global warming
  2. 2.Fragmentation of habitat
  3. 3.Invasion of alien species
  4. 4.Promotion of vegetarianism.

Select the correct answer using the codes given below:

  1. A.1, 2 and 3 only
  2. B.2 and 3 only
  3. C.1 and 4 only
  4. D.1, 2, 3 and 4
▶ Answer & Explanation

Correct answer: A. 1, 2 and 3 only

Global warming alters ecosystems, leading to species extinction and changes in distribution. Habitat fragmentation isolates populations, reducing gene flow and increasing vulnerability. The introduction of alien species often outcompetes native flora and fauna, disrupting ecological balance. Conversely, promoting vegetarianism can reduce pressure on land and resources, potentially benefiting biodiversity rather than threatening it.
