A small part of a population is relocated to a completely new environment. Since only a few individual are moved, the gene pool in that group is severely reduced. Mark all that apply. A. Founder Effect
B. Gene Flow
C. Genetic Drift
D. Bottleneck

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.
