Grade 4 students study ecosystem connections in this NGSS 4-ESS3 worksheet. They explore how bees pollinate crops, forests release oxygen, and clean water supports drinking and farming. Fill-in-the-blank items and a four-pair matching section reinforce key terms like ecosystem, biodiversity, and conservation while showing how living things and natural resources depend on one another for survival every day. Grade 4 students see ecosystem connections.
