Help your students build real understanding of ecosystem response to disturbance through ninety questions that move from basic recognition to genuine reasoning about living systems.
Among the ninety questions, students will see prompts such as "Which human activity is most likely to result in a permanent change to an ecosystem?", "Which type of disturbance would most likely trigger primary succession?", and "Which of the following is a common recovery mechanism in wetlands post-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 Stability and Change in Ecosystems, Biodiversity and Ecosystem, Succession in Ecosystems, 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.
