Welcome to the NCERT Solutions for Class 9 Science - Chapter Natural Resources. This page offers a step-by-step solution to the specific question from Exercise 0, Question 38: . With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.

Question 38:

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:

All living organisms are basically made up of carbon, nitrogen, sulphur, phosphorus, hydrogen and oxygen. These chemical elements tend to circulate in the biosphere in a characteristic cyclic path, i.e., from environment to living organisms and back to the environment. These more or less circular paths are called biogeochemical cycles or nutrient cycles. In simple ways, these elements are absorbed by the plants from nature and convert them into food. This food passes through different trophic levels of various food chains for utilization by consumers. Finally, the decomposers return the inorganic nutrient to the environment by decomposing the dead bodies and excreta of various consumers.
