Describe an investigation you could do to show how much more a normal plant grows compared with a variegated plant over a six-week period.
In your answer, you must clearly identify:
the independent variable (IV)
the dependent variable (DV)
the variables to control (CV)
how you will calculate the end result.

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.
