They will later learn about relationships – cycles, chains, webs – that are created as a result of these energy flows within the system and their inter- relationship.
Ecosystem – Structure and Function, Productivity, Decomposition, Energy Flow, Ecological Pyramids, Ecological Succession, Succession Of Plants, Nutrient Cycling, Ecosystem – Carbon Cycle, Ecosystem – Phosphorus Cycle and Ecosystem Services are the main topics discussed in this chapter. Diagrams, illustrations, figures, graphical representation and lucid language make this chapter comprehensive and easy to learn. Sequential progress of topics helps to grasp and retain better.
