Biology ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on invasive species and ecosystem, aligned to the same NGSS performance expectation.
The set includes questions like "What role do invasive species play in ecosystem service disruption?", "How can invasive species affect nutrient cycling in an ecosystem?", and "Why are ecosystems with low biodiversity more susceptible to invasive species?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a complete NGSS aligned biology unit. The unit also covers Resources and Population Size, Competition in Ecosystems, Symbiotic Relationships, Predator Prey Dynamics, Niches and Habitat Use, and Keystone Species and Ecosystem, 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-LS2-1.
