Energy Sources and Food Chains

The video tutorial by Teacher Siri from the Wave Private School introduces the concept of food chains, explaining how organisms obtain energy either directly from plants or indirectly from other animals. It covers the interdependence of living organisms within habitats, the process of photosynthesis, and the storage of starch in plants. The tutorial also discusses energy transfer in ecosystems, highlighting the roles of producers, consumers, and decomposers. Students are engaged with activities to identify plant and animal-based food sources and understand feeding relationships.
