• The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
• Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.
  

So, the correct answer is 'The carbon cycle'.

The plants can fix carbon dioxide from the atmosphere which is taken in through stomata. The carbon dioxide is converted in the presence of light and chlorophyll pigments to synthesize carbon containing organic compounds such as sugar, fats and proteins. This creates the plant biomass which when eaten by other organisms recycles the carbon from on level to other. Finally the carbon enters the geosphere and then the atmosphere. The oxygen which is formed during photosynthesis is liberated in the atmosphere and used for cellular respiration. The oxygen is used to break down the molecules and release the carbon dioxide. The carbon gets recycled in the environment from plants to animals and then again enters the environment. 

Answer is option A i.e. "Low stability and high resilience"
Stability is the power of a system to be in their state against unfavorable factor. Resilience is the capability of regaining its original shape or position after being deformed. An ecosystem which can be easily damaged but can recover after sometime when it 's damaging effect stops will be having low stability and high resilience. Hence, it has low stability and high resilience.

During summer the land becomes dry and rainfall induces formation of grass and hence heavy rainfall during summer produces grasslands.

Plants take nitrogen from the soil by absorption through their roots as nitrate ions and ammonium ions.Nitrite is intermediate and gets converted to either forms by symbiotic or non-symbiotic bacteria present in plant roots and soil respectively.  Most nitrogen obtained by terrestrial animals can be traced back to the eating of plants at some stage of the food chain.

Salvia, Morus, Euphorbia are pollinated by insects (entomophily)

Carbonization (or carbonisation) is the term for the conversion of an organic substance into carbon or a  carbon containing residue through destructive distillation or pyrolysis (also occurs in nature). It is often used in organic chemistry with  reference to the generation of coal gas and coal tar from raw coal.

Phanerogamae are the sub-kingdom of kingdom Plantae. They include seed bearing and flowering plants. They are further grouped into angiosperms and gymnosperms. Gymnospermic plants are pollinated by wind that is anemophilous.
