What is the wave velocity if the wave length is 200 cm and the frequency is 4 Hz?

λ-wavelength=200cm=2m

f-frequency=4Hz

v-velocity=?

λ=v/f=>v=λ*f=2m*4Hz=8m/s

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.
