Questions Related to biodiversity on earth and in india

The study of total number and types of organisms present on earth is

  1. Ecology

  2. Taxonomy

  3. Biodiversity

  4. Classification


Correct Option: C
Explanation:

Biodiversity is the term used to describe the variety of life found on Earth and all of the natural processes. This can refer to genetic variation, ecosystem variation or species variation within an area, biome or planet. The biodiversity is more concentrated within the tropical ecosystems than temperate ecosystems. The most diverse group of animals are invertebrates. 
Some human activities have indirect but wide-reaching effects on biodiversity, including climate change and pollution. These threats have put a serious strain on the diversity of species on Earth.

Variety of organisms in different ecosystem can be measured by 

  1. Genetics

  2. Microbiology

  3. Biodiversity

  4. All of the above


Correct Option: C
Explanation:

Biodiversity is the measure of the variety of life on the earth. It can refer to genetic variation, ecosystem variation, or species variation within an area, biome, or planet. Thus, the correct answer is option C.

................ is a measure of the variety of organisms present in different ecosystems.

  1. Environment

  2. Biodiversity

  3. Generation

  4. None of the above


Correct Option: B
Explanation:

Biodiversity, a contraction of "biological diversity," generally refers to the variety and variability of life on the Earth. One of the most widely used definitions defines it in terms of the variability within species, between species and between ecosystems. It is a measure of the variety of organisms present in different ecosystems.  

Biodiversity consists of variety of

  1. Plants

  2. Animals

  3. Organisms

  4. All of the above


Correct Option: D
Explanation:

The different variety of life forms is known as biodiversity which includes plants, animals and microorganisms where they interact with each other and maintain the ecosystem. Thus, the correct answer is option D.

Convention of biodiversity came into force on

  1. 29 December 1993

  2. 6 June 1992

  3. 3 October 1994

  4. 4 October 1993


Correct Option: A
Explanation:

The Earth Summit was held in Rio de Janeiro in Brazil in 1992. Earth summit at Rio, Brazil, promoted 'Convention on Biological Diversity' (CBD), which was signed by 152 nations. Its recommendations came into effect on 29th Dec. 1993. India became a party to this 'Convention on Biological Diversity' in May 1994.

Alpha diversity is biodiversity present

  1. Within community

  2. Between community

  3. Ranges of communities

  4. All of the above


Correct Option: A
Explanation:

The local species pool is known as alpha diversity. It is also the diversity present within the community. Beta diversity is the diversity present between the communities. The diversity present in the ranges of communities is known as Gamma diversity.

So, the correct answer is 'Within community'.

Biodiversity is determined by

  1. Number of individuals in an area

  2. Species richness

  3. Evenness

  4. Both B and C


Correct Option: D
Explanation:

The variety and variability of living organisms (both plants and animals) are known as biodiversity. The variation measured by biodiversity is at the genetic, species, and ecosystem level. Species richness and evenness are major factors determining biodiversity. Tropics have the highest biodiversity.

So, the correct answer is 'Both B and C'.

Biodiversity act of India was passed by Parliament in

  1. 1992

  2. 1996

  3. 2000

  4. 2002


Correct Option: D
Explanation:

An Act of the Parliament of India for the preservation of biological diversity in India was passed in 2002 known as the Biodiversity Act of India. This act provides methods for the sharing of benefits in an equitable manner arising out of the use of traditional biological resources and its knowledge. The function of this act includes: Regulation of acts prohibited under the Act, Advise the Government on the conservation of biodiversity, etc. Any offense under this Act is non-bailable and cognizable.

So, the correct answer is '2002'.

India became a party to convention on biological diversity in

  1. 1994

  2. 1993

  3. 1992

  4. 1988


Correct Option: A
Explanation:

The Earth Summit of Rio de Janeiro, also known as the United Nations Conference on Environment and Development (UNCED), was held in Rio de Janeiro from 3 to 14 June 1992. It resulted in the Convention on Biodiversity, a multilateral treaty. Three major goals were addressed in this convention which included: conservation of biodiversity; sustainable use of its components; and the fair and equitable sharing of benefits arising from the genetic resources. India became a party to Convention on Biological Diversity in '1994'.
So, the correct answer is '1994'.

World biodiversity day is

  1. 22$^{nd}$ April

  2. 16$^{th}$ September

  3. 5$^{th}$ June

  4. 22$^{nd}$ may


Correct Option: D
Explanation:
Biodiversity day or the Biological diversity day is a UN sanctioned day celebrated internationally. It addresses the promotion of biodiversity issues. Currently, the day is held on May 22. Earlier, it was held on December 29 to celebrate the day in which the Convention on Biological Diversity came into action.
So, the correct answer is '22 May'.
