Food chain and food web

खाद्य शृंखला और खाद्य जाल

In this Class 10 Science topic from “Our Environment,” students learn how energy and nutrients move through an ecosystem. They explore the roles of producers, consumers, and decomposers, and understand trophic levels through examples of food chains. By comparing several connected food chains, students see how a food web represents feeding relationships more realistically. The topic also explains how changes in one population can affect others, helping students understand ecological balance and the flow of energy in nature.
