Question 1
1 / -0

A fungus that is predator of a species of frog have killed 50 frogs to save this species of frog scientist set other 35 frog to a different area then tell which process will save this type of frog species?

A
Bottle neck effect

B
Founder effect

C
Big bang theory

D
Natural selection
Solution
A- Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck doesn't last for very many generations.
B- A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have:
- reduced genetic variation from the original population.
- a non-random sample of the genes in the original population.
So, the correct option is 'Option A'.
Question 2
1 / -0

Write the correct sequence of genetic diversity.

A
Kingdom $$\rightarrow$$ Population $$\rightarrow$$ Species $$\rightarrow$$ Genes $$\rightarrow$$ Chromosome $$\rightarrow$$ Nucleotides

B
Population $$\rightarrow$$ Species $$\rightarrow$$ Chromosomes $$\rightarrow$$ Genes $$\rightarrow$$ Nucleotides

C
Species $$\rightarrow$$ Genes $$\rightarrow$$ Population $$\rightarrow$$ Chromosomes $$\rightarrow$$ Nucleotides

D
Kingdom $$\rightarrow$$ Species $$\rightarrow$$ Chromosomes $$\rightarrow$$ Genes $$\rightarrow$$ Nucleotides

Solution

Genetic diversity is the total number of genetic characteristics present within and among individuals of a population and species. It helps individuals to adapt to changing environments. Variation in the nucleotides in different species bring about the genetic diversity. Hence, nucleotide is the basic unit in the sequence of genetic diversity. It is followed by genes which is further followed by chromosomes and then species. Kingdom is the highest unit in the sequence of genetic diversity as it includes all the species.
Thus, the correct answer is option D.
Question 3
1 / -0

In which city are the headquarters of Zoological Survey of India situated?

A
Delhi

B
Thiruvananthapuram

C
Kolkata

D
Guwahati
Question 4
1 / -0

Species diversity ______ as we move away from the ______ towards_____.

A
decreases, equator, poles

B
increases, equator, poles

C
decreases, poles, equator

D
none of these.

Solution

The biodiversity shows a latitudinal and altitudinal gradient. The species diversity decrease as well as we move away from the equator towards the poles with very few exceptions, tropics harbour more species than temperature or polar areas.
Question 5
1 / -0

Western ghats have a greater number of amphibian species than the Eastern ghats. What kind of diversity does it represent?

A
Species diversity

B
Genetic diversity

C
Ecological diversity

D
None of these.

Solution

Species diversity is the variety in the number and richness of the species of a region, Western Ghats have greater amphibian species diversity as compared to eastern ghats.
So, the correct answer is option A.
Question 6
1 / -0

The diversity of organisms sharing the same habitat or community is termed as

A
alpha diversity

B
beta diversity

C
gamma diversity

D
delta diversity.

Solution

Ecological diversity is of three types:
(i) Alpha diversity
(ii) Beta diversity
(iii) Gamma biodiversity.
Question 7
1 / -0

Which of the following statements regarding the estimates of number of species found on earth is not correct?

A
Total number of species present on earth are considered to be about 7 million as estimated by Robert May.

B
Plants constitute more than 70% of all the species recorded, whereas animals constitute less than 22% of the total number of species.

C
Insects constitute more than 70% of all the animal species.

D
None of these.

Solution

Animals constitute more than 70% of all the species recorded whereas plants constitute around 22% of total number of species.
Question 8
1 / -0

The term biodiversity is popularised by

A
Odum

B
Paul Ehrlich

C
Edward Wilson

D
Tilman.

Solution

Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organisation. He is regarded as the Father of Biodiversity.
Hence the correct option is C.

Question 9

1 / -0

Study the given populations and choose the correct answer in relation to species diversity.

Population	Species	Group	Individuals
Population A	I	Mammals	3
	II	Birds	2
	III	Amphibians	2
Population B	I	Mammals	2
	II	Mammals	2
	III	Amphibians	1
Population C	I	Mammals	3
	II	Mammals	2
	III	Mammals	1

Maximum diversity - Population B;
Minimum diversity - Population C

Maximum diversity - Population A;
Minimum diversity - Population C

Maximum diversity - Population A;
Minimum diversity - Population B

Maximum diversity - Population B;
Minimum diversity - Population A

Solution

Species diversity is the number of different species present in a given population i. e. 'Species diversity relates to the number of different species.'
In population A, there are 3 different classes present. These are mammals, birds, and amphibians. Hence, it will have vast species diversity.
In population B, only 2 classes are present, namely mammals and amphibians. Hence, species diversity will be less compared to that of population A.
In population C, all the species belongs only to class mammals. Hence, it will show the least species diversity.

So the correct answer is option B.

Question 10
1 / -0

India has a greater ecosystem diversity than a Scandinavian country like Norway. What kind of diversity does it represent?

A
Species diversity

B
Ecological diversity

C
Genetic diversity

D
None of these.

Solution

Ecological diversity is the diversity at ecosystem level. India with its deserts, rainforests, mangroves, coral reefs, wetlands, estuaries and alpine meadows has a greater ecosystem diversity than a Scandinavian country like Norway.
