**will give brainliest** imagine a scenario when a scientist or engineer would need to measure or calculate volume of something accurately. you read about the air canada flight, where the grounds crew needed to use the correct conversion factor to fill the planes fuel tank. what other scenarios might it be important to measure or calculate volume correctly, and why? **describe what would be measured and why it would be important to measure it accurately.**

Units can be in metric form and imperial form. The metric form is considered to be a scientific standard around the world. It is adopted by the system internationale as SI units.

There are several scenarios where a careful use of the unit is a must. They are:

it will increase due to the time span

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.
