Nitrogen Cycle steps:

N molecules breaking apart via nitrogen-fixing bacteria.

Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.

The organic matter decays via decomposers

N2 is formed via denitrifying bacteria.

Explanation:

The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.

Animals (herbivores) consume the plants that have absorbed nitrogen/

When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia

The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.

The nitrogen thus formed is released to the atmosphere

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped sporangium, which is the *sporophyte stage of the plant*. The sporangium contains spore sacs, each of which is the spore mother cell that undergoes meiotic division to form four spores,The spores are released and germination

takes place giving rise to a protonema, which develops into a new gametophyte plant. The gametophyte generation or haploid phase of the moss is from the production of haploid spores after meiosis to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid phase is from the diploid mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
