The process of photosynthesis can be represented by the chemical formula a) c6h12o6 + 6o2 → 6co2 + 6h2o + energy b) c6h12o6 + 6h20 → 6co2 + 6h2o c) 6co2 +6h2o + light → c6h12o6 + 6o2 d) 6co2 + 6h2o → c6h12o6 + 6o2

Option C,

Explanation:

In the process of photosynthesis, the following raw material are chemically combined in the presence of light (obtained from sun) -

a) carbon dioxide

b) water

to produce  glucose and oxygen.

If we write a chemical equation for above process it will be as follows -

where A is the symbol used for sunlight.

Thus, option C is correct

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
