Which of the following are the reservoirs for Phosphorous and Nitrogen cycle respectively?
1 Atmosphere and Bedrocks
2 Bedrocks and Atmosphere
3 Atmosphere and producers
4 None of these
Explanation:
Phosphorous recycling is a sedimentary cycle, where as nitrogen recycling is a gaseous cycle.

Source of maximum sulphur is
1 Lakes
2 Oceans
3 Land
4 Rocks
Explanation:
Sulphur recycling is a sedimentary cycle, hence rocks are good source of sulphur.

The reservoir for the gaseous type of bio-geo chemical cycle exists in
1 Stratosphere
2 Atmosphere
3 Ionosphere
4 Lithosphere
Explanation:
For gaseous biogeochemical cycles atmosphere acts as reservoir.

Statement A : Atmospheric inputs of phosphorus through rainfall are much larger than carbon inputs. Statement B : Gaseous exchanges of phosphorus between organism and environment are negligible.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs

Which in not correct statement from the following
1 Food web shows the pattern of energy or nutrient flow throughout the community
2 Carbon cycle does not necessarily have to involve decomposers
3 The organisms, which attack dead animals are present at the starting of food chain, e.g. detritus food chain and are known as decomposers.
4 Cropland ecosystem is a man made ecosystem. Here genetic diversity is least and food web is simple
Explanation:
Carbon cycle is a type of gaseous cycle. In carbon cycle, decomposers are involved in decomposition of organic wastes and dead bodies to release carbon.
