CBSE Notes Class 8 Science Chapter 12 How Nature Works in Harmony

Nature is a balanced system of biotic (living) and abiotic (non-living) factors. Energy flows through food chains—starting with plants (producers) and moving to animals (consumers). Decomposers recycle nutrients back into the soil.

Maintaining this ecological balance is vital; if one part of the chain breaks, the whole ecosystem suffers. Students learn about ecosystems, food chains, and environmental balance. These CBSE Class 8 Science notes promote awareness about conservation.
