How can you say that photosynthesis is the basic energy source for living world

we can analyse this topic by taking a look at the reaction of photosynthesis

CO2+H2O+LIGHT>C6H12O6+O2

we can see that one form of energy(light energy) has been stored in the chemical bonds(glucose)

if we look at the chemical reaction for aerobic respiration(the way we obtain energy)

C6H12O6+O2CO2+H20+energy

we can see that the energy stored in the bonds has been released

also respiration reactants are photosynthesis produts

Wishing you and your family health, happiness, peace and prosperity this Christmas and in the coming New Year.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

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.
