This is the study guide I use to help prepare my students for their unit test during our ecosystems unit using the fourth grade standards.
~roles of producers, consumers, and decomposers
~flow of energy through a food chain
~how changes in the environment and food chain would affect the community and ecosystem
~What happens if there are too many or a scarcity of organisms in a food chain
~Adaptations and how they help
~Extinction-factors that contribute to and how we can help
I hope you and your class finds this study guide as useful as we do! Please let me know if you have any questions.
