Which vocabulary words should be most appropriate for a teacher to pre-teach in a unit on ecosystems?

In a unit focused on ecosystems, pre-teaching vocabulary words that are conceptually challenging is particularly beneficial for students. This is because the study of ecosystems involves complex ideas and relationships, such as food chains, biomes, and interdependence among organisms. These challenging words help students grasp the essential concepts necessary to understand and engage with the content more deeply.

By focusing on conceptually challenging vocabulary, teachers can scaffold student learning, providing them with the foundational language needed to discuss and analyze ecological concepts. This approach encourages critical thinking and helps students develop a nuanced understanding of the material. Additionally, understanding these terms will enhance their ability to comprehend texts and participate in discussions related to ecosystems.
