Check the statements about light-independent reactions in photosynthesis that are true. light-independent reactions requires carbon dioxide (co2). light-independent reactions occur in the thylakoid membrane. light-independent reactions involve the splitting of water molecules. light-independent reactions produce carbohydrates.

the first and last one are right

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.
