14. In Ecology, an ecotone is a/an:
[A] transition zone between two biomes
[B] community plus its physical environment
[C] association between a species and a group of sites
[D] distinct geographic variety within a species
Show Answer
Correct Answer: A [ transition zone between two biomes ]
Notes:
The transition zone where two communities or biomes meet and intergrade is called an ecotone. Ecotone may vary in range starting from small agricultural field to large forest.
15. The Leq symbol is used in measuring which of the following kinds of pollutions?
[A] Air
[B] Water
[C] Noise
[D] None of them
Show Answer
Correct Answer: C [Noise]
Notes:
As per the ambient noise standards, that have been notified for different categories like, industrial, commercial and residential areas and silence zones etc, for residential areas, 55 dB (A) Leq during ‘day time’ and 45 dB (A) Leq during ‘night time’ for residential areas have been fixed. Leq is a symbol that represents “Equivalent Continuous Noise Level”. Usually the signal that you are measuring is varying in amplitude.Leq noise levels are logarithmic (dB) values and cannot be added directly. A doubling of sound level results in a measured increase of 3 dB, four identical sources in a room would increase the noise level by 6 dB and so on.

Show Answer
Correct Answer: C [Nitrogen dioxide]

Show Answer
Correct Answer: D [1, 2 & 3 ]
Notes:
An ecosystem is formed by the interaction of biotic and abiotic factors. Niche is formed in an ecosystem. An ecologoical niche is the role and responsibility of an organism in its environment formed due to its interaction with biotic and abiotic factors of an ecosystem. It includes things like food habit, habitat, functional interaction etc. No two species can have exactly same niche in an ecosystem. They can have overlapping niches to some extant but not the same.
A ecotone is formed with the interaction of two different biological community thus forming a transitional area having its own ecosystem. Example- Mangroves.
