This resource turns investigating organism interactions into a complete, ready to use review for Grade 6-8 biology, covering the same NGSS standard from three different angles.

Sample questions include "In an ecosystem, which of the following would be considered a biotic factor?", "What is the primary role of predators in an ecosystem?", and "In an ecosystem, which of the following is an abiotic factor that affects organism interactions?"

• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 26 pages in total

Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.

• Review before a lab or class discussion
• Self checking stations, since every answer key includes explanations
• No prep cover lesson for a substitute teacher
• Bell ringers and warm ups during the unit

This set is part of a complete NGSS aligned biology unit. The unit also covers Modeling Symbiotic Relationships, Effects of Population Change, Ecosystem Disruption and Recovery, and Patterns of Resource Use, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.

Suitable for Grade 6-8 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard MS-LS2-1.
