Grade 8 Science Ecosystems worksheets

📚 Topic Summary

An ecosystem is a community of living things (plants, animals, and microorganisms) that interact with each other and their non-living environment (air, water, soil, and sunlight). These interactions create a delicate balance where energy and nutrients flow between different organisms. Understanding ecosystems helps us appreciate the interconnectedness of life and the importance of protecting our environment.
