Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In our biosphere immense diversity (or heterogeneity), exists not only at the species level but at all levels of biological organisation ranging from macromolecules within cells to biomes. Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organisation. The most important of them are- 
(i) Genetic diversity.
(ii) Species diversity.
(iii) Ecological diversity.

  2. 45,000

  3. 58,000

  4. 80,000
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

India is one of the richest countries when it comes to the diversity of plant species. Around 45,000 plant species are estimated to be present in India. There are eight main florist regions in India which are Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar, and the Andaman Islands. So, great efforts for protecting the immense biodiversity should be done.

So, the correct answer is '45,000'.

Which of the following is incorrect?

  1. Stellars Sea Cow and Passenger Pigeon got extinct due to over exploitation

  2. <p>Lantana and Eichhornia are invasive weed species in India</p>

  3. Species diversity increases from equator to poles

  4. Convention on biological diversity was held in 1992

  5. Among animals, insects are the most species rich taxonomic group
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Species diversity decreases from equator to poles. The reason lies behind the fact that the conditions for the survival of species at poles become unfavorable. The Equator has favorable conditions for the survival of wildlife. Good vegetation, sunlight, and habitat these factors are responsible for great biodiversity at the equator.

So, the correct answer is 'Species diversity increases from equator to poles'.

Which one shows maximum genetic diversity in India?

  1. Groundnut

  2. Rice

  3. Maize

  4. Mango
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Genetic diversity represents the total number of genetic characteristics in the genetic makeup of a species. Whereas, the genetic variability describes the tendency of genetic characteristics to vary. This diversity lets the population adapt to changing environments. For example, In India, we find mangoes with different flavors, colors, fiber content, sugar content, and shelf life, as it has the greatest genetic diversity in our country. The great variation is due to the genetic diversity. 
So, the correct answer is 'Mango'.

Which region is rich in species diversity?

  1. North Pole

  2. Temperate region

  3. Tropical region

  4. South Pole
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Species diversity increases towards the equator. The two main reasons are phylogenetic niche conservatism and ecological productivity. The relatively high temperatures in the tropics generate and maintain high diversity. However, the tropical rainforests in developing countries are getting cleared nowadays, which is leading to a great loss of biodiversity.

So, the correct answer is 'Tropical region'.
