Cycling of elements in any ecosystem is called as

  1. Chemical cycle

  2. Geochemical cycle

  3. Biogeochemical cycle

  4. Geological cycle

Show answer
Correct Option: C
Explanation:

In earth science, a biogeochemical cycle or substance turn over or cycling of substances is a pathway by which a chemical substance moves through both biotic and abiotic (lithosphere, atmosphere and hydrosphere) compartments of Earth. A cycle is a series of change, which comes back to the starting point and which can be repeated.

The utilization of elements and compounds in nature and their subsequent return to the environment is called

  1. Life cycles

  2. Cyclic pathway

  3. Material cycles

  4. Recycling

Show answer
Correct Option: C
Explanation:

The utilisation of elements and compounds in nature and their subsequent return to the environment is called material cycles. It is also called as a biogeochemical cycle. 
In biology, a life cycle is a series of changes in form that an organism undergoes, returning to the starting state.
Recycle is the conversion of waste into useful forms.
Cyclic pathways tend to use the last product they create to re-begin the cycle. 

So, the correct answer is option C.

Biogeochemical cycling means cycling of

  1. Energy in ecosystem

  2. Gases between plants and the atmosphere

  3. Nutrients in an ecosystem

  4. None of the above

Show answer
Correct Option: C
Explanation:

Biogeochemical cycle is a pathway by which a chemical substance moves through both biotic and abiotic compartments of earth. The circulation of chemical nutrients like carbon, oxygen, nitrogen, phosphorus, calcium and water, etc., through the biological and physical world are known as biogeochemical cycles. In effect, the element is recycled, although in some cycles there may be places where the element is accumulated or held for a long period of time.

Which one of these is a sedimentary cycle?

  1. Phosphorous

  2. Hydrogen

  3. Oxygen

  4. Nitrogen

Show answer
Correct Option: A
Explanation:

Phosphorus cycle is an example for sedimentary cycle. 

A cycle which comprises the weathering of an existing rock, followed by the erosion of minerals, their transport and deposition, then burial, is called as sedimentary cycle. 
First cycle sediments are characterized by the presence of less resistant minerals and rock fragments. If this material is reworked through a second cycle, the less resistant minerals will be eliminated or altered to more stable products. 
The more sedimentary cycles, that a sediment has passed through the more mature, it will become and it will be dominated by well rounded resistant minerals.

The flow of materials from non living components to living components and back to the non living components in a more or less cyclic manner is called as

  1. Gaseous cycle

  2. Sedimentary cycle

  3. Biogeochemical cycle

  4. Hydrologic cycle

Show answer
Correct Option: C
Explanation:

A biogeochemical cycle or inorganic-organic cycle is a circulating or repeatable pathway by which either a chemical element or a molecule moves through both biotic (bio-) and abiotic (geo-) compartments of an ecosystem. 

Source of maximum sulphur in reservoir of sulphur is

botany energy flow in an ecosystem biogeochemical cycle nutrient cycles species, communities and ecosystems

  1. Ocean

  2. Lakes

  3. Rocks

  4. Both A and C

Show answer
Correct Option: D
Explanation:

The ocean represents a major reservoir of sulphur on earth, with large quantities in the form of dissolved sulphate and sedimentary minerals (e.g., gypsum and pyrite). Sulphate is the most stable form of sulphur on earth; weathering and leaching of rocks and sediments are its main sources to the ocean. The majority of sulphur is found in seawater or sedimentary rocks especially pyrite rich shales and evaporite rocks. 

Therefore, the correct answer is option D.

Biogeochemical cycles are also known as

botany energy flow in an ecosystem biogeochemical cycle nutrient cycles species, communities and ecosystems

  1. Cycles of matter

  2. Sedimentary cycles

  3. Material cycling

  4. Gaseous cycles

Show answer
Correct Option: A
Explanation:

Biogeochemical cycles may also be referred to as cycles of matter because they link together all organisms and abiotic features on earth. Matter is continually recycled among living and abiotic elements on earth. Biogeochemical cycles facilitate the transfer of matter from one form to another and from one location to another on planet earth.

Therefore, the correct answer is option A.
