  1. 533

  2. 839

  3. 1724

  4. 3700

Show answer
Correct Option: A
Explanation:

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, small population, and position at a higher trophic level favour extinction. 533 animal species have become extinct since 1600 AD.

So, the correct answer is '533'.

Number of plant species known to have become extinct since 1600 AD is

  1. 279

  2. 384

  3. 629

  4. 717

Show answer
Correct Option: B
Explanation:

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, small population, and position at a higher trophic level favour extinction. 384 plant species have become extinct since 1600 AD.

So, the correct answer is '384'.

So, the correct answer is 'Endangered species'.

Which of the following statement is correct? 

biology main natural resources classification of threatened species red data book conservation of wildlife

  1. 99% of existed species are extinct

  2. 65% of existed species are extinct

  3. 40% of existed species are extinct

  4. 30% of existed species are extinct

Show answer
Correct Option: A
Explanation:
  • Calculating the percentage of existed species that are extinct can be difficult because no one knows exactly how many species there are. 
  • Scientists have identified that of all species that have existed on Earth, 99.9 % are now extinct. Many of them perished in five catastrophic events.
  • Hence 99% of existed species are extinct.
  • So, the correct answer is '99% of existed species are extinct'.
