What vocabulary pertains to subject-specific terms such as "photosynthesis" and "habitat"?

The choice of Tier 3 vocabulary is appropriate because this tier consists of domain-specific terms that are used in particular fields of study. Words like "photosynthesis" and "habitat" are specialized language associated with science, particularly biology and ecology. These terms convey specific, nuanced concepts that are not typically encountered in everyday conversations.

Understanding Tier 3 vocabulary is essential for students as they engage with content in various subjects, enabling them to comprehend and communicate more effectively in academic settings. In contrast, Tier 1 vocabulary would include basic, everyday words; Tier 2 involves more complex words often encountered in written texts but not exclusive to specific subjects; and general vocabulary encompasses common language that does not necessarily imply a technical or subject-specific meaning. Therefore, identifying vocabulary as Tier 3 highlights its significance in specialized learning contexts.
