Species diversity
-
None of the above
Whittaker's idea was that the total species diversity in a landscape is the gamma diversity and is determined by two different things, the mean species diversity in sites or habitats at a more local scale is an alpha diversity and the differentiation among those habitats is the beta diversity.
Biodiversity-rich areas are the
-
Hotspots
-
Plants
-
Animals
-
None of the above
The variety of forms of life found in a region is called as

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
Given below are a few statements related to biodiversity. Pick those that correctly describe the concept of biodiversity.
-
Biodiversity refers to the different species of flora and fauna present in an area
-
Biodiversity is greater in a forest
-
Biodiversity refers to the total number of individuals of a particular species living in an area
-
Both A and B
Biodiversity refers to the different species of flora and fauna present in an area. It is a term coined to describe the immense variety and richness of life on this planet. The word was coined in 1985 and during the 1990s has become very widely used in the scientific circles. So, the correct answer is option D.
Which of the following shows the maximum diversity?
-
Algae
-
Fungi
-
Pteridophytes
-
Bryophytes
The term biodiversity implies only to organisms living in/on
-
Land
-
Forest
-
Water
-
All of the above
The term biodiversity means all life forms present all over the world, it implies to all organisms whether they live on land and water. Thus the correct answer is option D.
The term alpha diversity refers to
-
Genetic diversity
-
Community and ecosystem diversity
-
Species diversity
-
Diversity among the plants
How does the level of biodiversity change as an individual moves from the north pole to the equator?
-
The biodiversity increases and then decreases.
-
The biodiversity decreases and then increases.
-
The biodiversity increases.
-
The biodiversity does not change significantly.
-
The biodiversity rapidly decreases.
Biodiversity increases as one moves from North pole towards the equator. The North pole has an extremely cold climate that requires specialized adaptations for organisms to dwell, moreover resources are few.
Which is accepted by researchers as a level of biodiversity?
II. Genetic biodiversity
III. Ecosystem biodiversity
-
I only
-
II onIy
-
I and II only
-
II and III only
-
I, II and III
- Researchers have accepted three levels of biodiversity, namely genetic biodiversity, species biodiversity, and ecosystem biodiversity. All three levels are interrelated.
- Genetic diversity includes variety at the level of genes. It is measured at various levels like population, species, community, and biome.
- Species diversity includes variety in the species. It is the easiest method of studying diversity. Each species has a particular role in the ecosystem.
- Ecosystem diversity includes diversity that deals with species distribution, community patterns, the role of key species and species interactions.

The Earth's Summit was held at 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 29$^{th}$ Dec, 1993. India became a party to this 'Convention on Biological Diversity' in May 1994.
