Number of endangered species of angiosperms in India is

  1. 487

  2. 3000

  3. 5000

  4. 15,000

Which group of vertebrates among the following, comprises the highest number of endangered species?

  1. Birds

  2. Mammals

  3. Fishes

  4. Reptiles


Correct Option: B
Explanation:

An endangered species is a species that is at high risk of becoming extinct. Plants have the highest number of endangered species. Mammals have 177 endangered species which represents 3.8% of all the species. Similarly, birds have 188 endangered species which represents 1.9% of all the species. Reptiles, amphibians and fishes have 47, 32 and 158 endangered species representing 0.7%, 0.7% and 0.6% respectively of all the species in each group.

Thus, the correct answer is option B.

Archaeopteryx is

  1. Extinct mammal

  2. Extinct bird

  3. Star Fish

  4. Marine fish


Correct Option: B
Explanation:
Arcahaeopteryx is an extinct bird. It is the most primitive known bird with several specimens dating back about 150 million years to the Jurassic bird. It is also known as an evolutionary link between modern birds and a group of dinosaurs that roamed the earth 150 million years ago.
So, the correct answer is 'Extinct bird'.

Number of animal species having become extinct since 1600 AD is

  1. 533

  2. 839

  3. 1724

  4. 3700


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


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'.

According to IUCN Red List, what is the status of Red Panda (Ailurus fulgens) ?

  1. Critically endangered species

  2. Vulnerable species

  3. Extinct species

  4. Endangered species


Correct Option: D
Explanation:
Red Panda (Ailurus fulgens) is listed as Endangered species according to IUCN Red List because the wild population is estimated at fewer than 10,000 mature individuals and continue to decrease due to habitat loss and fragmentation, poaching and inbreed depression.
So, the correct answer is 'Endangered species'.

Which of the following statement is correct? 

  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


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'.

Cheetah (Acinonyx jubatus) has become extinct from

  1. Srilanka

  2. India

  3. Africa

  4. Malaysia


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. Cheetah has become extinct from India.

So, the correct answer is 'India'.

Mass extinction of species has occurred during

  1. Permian

  2. KT Boundary

  3. Pleistocene

  4. All of the above


Correct Option: D
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. Mass extinction of species has occurred during Permian, KT Boundary and Pleistocene period.

So, the correct answer is 'All of the above'.
