you take a trip from your home to Mali, a very poor country in western Africa. How is the water usage you observe there likely to be different from how water is used in your home city?

you are the source of the heat energy. you can minimize the heat energy by selecting the appropriate clothes to wear.

what's the question?

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.
