Choose 2 of the following cycles (carbon, phosphorus, nitrogen, water) and describe each stage of them thoroughly.

Water-The entire process of water cycle takes place in almost five steps which includes the evaporation, condensation, precipitation, infiltration, and runoff. To begin with, water gets evaporated from the water bodies on the surface of earth like rivers, oceans etc. into the overlying atmosphere.

Nitrogen-The nitrogen cycle is split up into five main processes. These processes are nitrogen fixation, assimilation, ammonification, nitrification, and denitrification. Each of these play an important role in movement of nitrogen through the different ecosystems on earth.

a and c are the answeres

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
