Question

All the living organisms are basically made up of C, N, S, P, H and O. How do they enter the living forms? Discuss.

Answer 1

Hint: The elements like C, N, S, P, H and O are vital elements that help in formation of all the living organisms these elements pass into other organisms by plants from the food chain. These elements enter living beings through biogeochemical cycles.

Complete answer:
Every element enters through plants in the body of living organisms and helps in overall functioning of the body. These elements enter into the body of living organisms through plants as these elements first enter into plants by active absorption or by photosynthesis.

Phosphorus and sulphur enters into living organisms by plants from the soil and enters into the animal's body through food and water. Respiration processes help to enter oxygen elements into the living organisms which help in performing various processes in our body. Hydrogen element enters into the living organism through food and water and another source of hydrogen element is absorbed water. Nitrogen uptake occurs in plants in the form of nitrates and nitrites from the soil which converts them into proteins. These elements are then entered into the animal's body as they consume food and help in optimum growth and functioning of the animal body.

Note: All these elements enter the animal through plants indirectly or directly. Therefore, we can say that all basic elements are made up of C, N, S, P, H and O enters into living organisms by one way or the other with the help of plants as plants are only the basic need of living organisms as plants are autotrophs and make their food on their own.
