This resource turns stability and change in ecosystems into a complete, ready to use review for Grade 9-12 biology, covering the same NGSS standard from three different angles.
Among the ninety questions, students will see prompts such as "Which factor most directly contributes to the stability of an ecosystem?", "How do trophic cascades affect ecosystem stability?", and "What can enhance the stability of an ecosystem after a disturbance?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a complete NGSS aligned biology unit. The unit also covers Biodiversity and Ecosystem, Succession in Ecosystems, Ecosystem Response to Disturbance, Climate Change and Ecosystems, Habitat Fragmentation and Loss, and Modeling Ecosystem Change, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-LS2-2.
