Our Environment

When you explore Science, Chapter “Our Environment”, NCERT, you begin to understand how plants, animals, microorganisms, and humans depend on one another. You notice how living things and non-living things together form an ecosystem, such as a forest, pond, or even a garden. You reflect on how every small change in nature affects the balance of life. This learning helps you see the environment as a connected system.

As you read closely, you strengthen your reading and vocabulary by learning words like ecosystem, producers, consumers, decomposers, and trophic level. You observe how green plants capture energy from sunlight and pass it on through food chains and food webs. You connect these ideas to how energy flows from one level to another and why energy reduces at each step. This practice builds clarity in science learning. Your confidence grows as you connect terms with real examples.

When you examine food chains and food webs, you build problem-solving and cognitive skills. You think about how removing one organism can disturb the whole system. You evaluate how harmful chemicals can move through food chains and become more concentrated at higher levels. You begin to form balanced views about why protecting every part of an ecosystem matters. This helps you understand the importance of biodiversity.
