Help your students build real understanding of ecosystem changes from factor through ninety questions that move from basic recognition to genuine reasoning about living systems.
The set includes questions like "What may occur if a keystone species is removed from an ecosystem?", "How does urban development impact local wildlife?", and "What can happen to a forest ecosystem if a logging company removes a large section of trees?"
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 standards aligned biology unit. The unit also covers Habitat Change and Population, Human Actions That Alter Habitat, Population Disruption, Ecosystem Disruption, Resource Changes and Species, and Outcomes of Ecosystem Disruption, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard LS.9.c.
