What process decreases the salinity of ocean water? decreased precipitationdecreased melting of glaciersincreased evaporationincreased runoff from rivers

increased runoff from rivers

Explanation:

Salinity of the ocean is the degree of concentration of salts in the ocean. It is the extent to which ocean water contains dissolved salt materials in it. It describes the saltiness of the ocean.

When runoff from rivers increases into an ocean, the salinity will reduce drastically. More fresh water implies a reduction in salt water content of the ocean. Runoff reduces or we can say dilutes the degree to which ocean water is salty.

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.
