Describe the magnifying power of a light microscope with that of an electron microscope.

Explanation:

Instead of using lenses and light to magnify a specimen, a scanning electron microscope uses electrons to create a magnified image. The specimen is placed at the bottom of a chamber and all the air is pumped out of the chamber, making it a total vacuum.

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.
