Write one appropriate word for statements given below and briefly explain them.
(i) The process by which carbon is incorporated into life forms.
(ii) The process by which nitrates are converted into free nitrogen.
(iii) The cyclic flow of nutrients like nitrogen and oxygen between nonliving environment and living organisms.
(i) Photosynthesis: CO2 is absorbed by plants in their habitat and converted to organic form. Energy comes from the sun. Water is the source of hydrogen.
(ii) Denitrification: Some bacteria present in the soil are in the water to ingest oxygen from nitrates for their activities. This replaces nitrogen with nitrogen by nitrogen gas.
(iii) Biogeochemical cycle: Bio-solidifying chemicals or nutrients are performed by organisms for structures and operations. When Organic remains, it will be posted later. The organism was taken the same.
