If there is a high death rate and large amount of
populations will likely decrease.

answer: oceans, duh

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

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.

the answer is c. altitude. hope this ! #brainiac
