Exploring Food Webs: Understanding Ecosystem Interactions

DESCRIPTION

In this grade 3 learning activity, students will investigate the intricate interactions between living things and their environment, specifically focusing on food webs. They will discover that every community contains multiple food chains and learn how organisms are interconnected through predation. By examining the relationships between predators and prey, students will write a paragraph describing the functioning of a food web, highlighting the roles of different organisms. This hands-on activity reinforces the concepts of ecology and the flow of energy within ecosystems.
