Questions Related to biodiversity, classification and conservation
Let no one species encroach over the right and privileges of other species is the stanza from
-
Atharva Veda
-
Isha Upanishad
-
Kautilyas Arthashastra
-
Bhagvat Geeta
Isha Upanishad is one of shortest Upanishads, which is embedded as the final chapters of Shukla Yajurveda, the following stanza is found in this upanishad.
Species diversity increases as one proceeds from
-
High altitude to low altitude and high latitude to low latitude
-
Low altitude to high altitude and high latitude to low latitude
-
Low altitude to high altitude and low latitude to high latitude
-
High altitude to low altitude and low latitude to high latitude
- Species diversity increases as one proceeds from high altitude to low altitude and high latitude to low latitude. The temperature and seasonal variability increases with increased altitude and decreased latitude. Hence, this results in higher species diversity in these areas.

Gymnosperms mean naked seeds; their ovules are naked and freely exposed to pollination, and the fertilized seeds are not enclosed by carpels. Great biodiversity exists on our planet. Millions of living plants and animal species are flourishing on Earth. An approximate of 1.7 million organisms are known to exist. 64 gymnosperm species are known from India.
A species spread over a large tract with varied environmental conditions will have
-
Higher genetic diversity
-
Uniform gene pool
-
Little genetic diversity

Either B or C
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. Gene-based diversity is known as genetic diversity. It is a way for populations to adapt to changing environments. A species spread over a large tract with varied environmental conditions will have higher genetic diversity.
In India, we find mangoes with different flavours, colours, fibre content, sugar content and shelf life. The large variation is due to
-
Genetic diversity
-
Species diversity
-
Induced mutations
-
Hybridisation
Beta diversity is diversity
-
In a community
-
Between communities

Beta diversity is the diversity present between the communities. It is also the rate of replacement of species along a gradient of habitats/communities. Whereas, the local species pool is known as alpha diversity and the diversity present in the ranges of communities is known as Gamma diversity.
The relation between species richness and area is correctly depicted by
-
log S = log C - Z log A
-
log S = Z log A
-
log S = log C + Z log A
-
log S = log C
-
log C = log S + Z log A
The relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area is described by the species-area curve. It says that log S = log C + Z log A. Here S is the number of species, A is the habitat area, and Z is the slope of the species-area relationship. Larger areas tend to contain larger numbers of species.
So, the correct answer is 'log S = log C + Z log A'.
Which scientist proposed alphaα types species diversity?
-
Bentham and Huxley
-
Linnaeus
-
Whittaker
-
Eichler
The local species pool is known as alpha diversity. It is also the diversity present within the community. The term was introduced by R. H. Whittaker. Example of such diversity includes high tree diversity throughout the Amazon Rainforests of Ecuador. Generally, gamma diversity = alpha diversity x beta diversity.
The number of taxa present within a particular area or an ecosystem is
-
$\alpha$ - diversity
-
$\beta$ - diversity
-
Gamma diversity
-
Delta diversity
The number of taxa present within a particular area or an ecosystem is called alpha diversity. It is also the diversity present within the community. The term was introduced by R. H. Whittaker. Example of such diversity includes high tree diversity throughout the Amazon Rainforests of Ecuador. Generally, gamma diversity = alpha diversity x beta diversity.
The species in which the evolutionary process has been influenced by man to meet his need is called.

Adventives species
-
Introduced species
-
Naturalized species
-
Domesticated species
