Biogeochemical Cycles
‘Bio’ refers to living organisms and ‘geo’ to the air, water and soil of the earth. Chemical elements tend to circulate in a characteristic path—from the environment to organisms and back to the environment. These more or less circular paths are known as biogeochemical cycles or nutrient cycles. Circulation of various nutrients between the living and nonliving components of ecosystems are called biogeochemical cycles. During these cycles, inorganic nutrients get converted into food. They are utilized by consumers and returned to the environment by de-composers. The four important biogeochemical cycles in nature are the carbon cycle, nitrogen cycle, oxygen cycle and water cycle. They help maintain a balance in our environment.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
