An endangered seal species consists of a single population. an earthquake divides its habitat, creating one large population of about 2,000 individuals and another, much smaller population of 50 individuals. describe how the genetic variation of the smaller population compares to the genetic variation of original population.

positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.

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.
