Question

Study the following and pick up the correct statements:

 I. Greater biodiversity is found in temperate regions 
II. Invasion of alien species is a threat for local species 
III. Loris tardigradus is one of the threatened species in our country 
IV. A biographic region with significant reservoir of biodiversity that is under threat of extinction from humans is called a sanctuary

• A. I, II
• B. II, III
• C. III, IV
• D. I, III

Hint:

Biodiversity hotspots are regions rich in endemic species and under threat from human activities. Examples include tropical rainforests and coral reefs.

Answer 1

The Correct Option is B

- I) Greater biodiversity is found in temperate regions: This statement is false. Biodiversity is generally richer in tropical regions compared to temperate regions. Tropical regions have a greater variety of species due to a stable climate and a higher amount of precipitation. - II) Invasion of alien species is a threat for local species: This statement is true. Alien (invasive) species often pose a significant threat to local species by outcompeting them for resources, spreading diseases, or disrupting the natural ecological balance. - III) Loris tardigradus is one of the threatened species in our country: This statement is true. Loris tardigradus, commonly known as the red slender loris, is a species found in Sri Lanka and is classified as endangered due to habitat loss and poaching. - IV) A biographic region with significant reservoir of biodiversity that is under threat of extinction from humans is called a sanctuary: This statement is false. A sanctuary is a protected area, but it is not necessarily characterized by the threat of extinction from human activities. The term "biodiversity hotspot" is typically used for such regions. Thus, the correct answer is II and III.
