Species classification and forest ecosystem science come together in this Grade 6 science resource, helping students explore how organisms obtain energy, how species are classified by their origins, and how changes in Alberta forests affect ecosystem balance. Students connect producers, consumers, and decomposers with native, introduced, invasive, and pest species while examining the ecological effects of mountain pine beetles.

Explore How Species Shape Forest Ecosystems

Students investigate two important ways scientists classify organisms. Functional classification describes how organisms obtain energy and contribute to ecosystems. Geographic classification distinguishes species that occur naturally in a region from those introduced beyond their original ranges. The resource uses white spruce as an Alberta native species example and mountain pine beetles to illustrate how organisms can change forest structure and wildlife habitats.

Students also examine why an introduced species is not automatically invasive or harmful. By considering abundance, location, interactions, and environmental conditions, they develop a more evidence-based approach to understanding ecosystem changes and potential management decisions.

What Students Practise

• Multiple-choice questions: Identify producers, consumers, and decomposers; recognize native and invasive species; and interpret the effects of mountain pine beetle outbreaks.
• True-or-false statements: Evaluate claims about energy acquisition, species origins, and ecosystem interactions.
• Short-answer responses: Explain organism roles, describe forest ecosystem changes, and justify why scientists investigate local conditions before selecting management actions.
• Diagram analysis: Trace energy from sunlight to plants and consumers and examine how fungi break down dead material.
• Classification activity: Sort written examples into native species and introduced or invasive species categories.

What's Included

• ✔️ A science reading passage introducing species classification and ecosystem balance
• ✔️ A printable student worksheet with varied question formats and a forest ecosystem diagram activity
• ✔️ Student Notes lines for recording key learning points
• ✔️ A separate Answer Key PDF with answers to support checking and review
• ✔️ A Teacher Guide within the Answer Key PDF, including learning objectives, teaching tips, discussion questions, and common mistakes

Practical Classroom Uses

Use this Grade 6 ecology and species classification practice during a lesson on trees and forests, as independent work after direct instruction, or as a review of organism roles and ecosystem interactions. The reading passage provides background before students apply vocabulary and reasoning skills across the activities. Diagram analysis gives students a visual way to connect energy flow with the roles of different organisms.

The included Teacher Guide supports lesson preparation and follow-up discussion. Use its prompts to explore how changing tree populations can affect habitat availability, why species impacts differ between environments, and what evidence scientists need before recommending management actions. The answer key also supports efficient checking and targeted reteaching.

Learning Beyond Memorizing Terms

This Alberta-focused forest ecosystem resource encourages students to connect classification with real ecological consequences. Rather than treating every introduced species as harmful, students consider the evidence behind species interactions and environmental change. It provides focused practice in scientific vocabulary, reading comprehension, classification, diagram interpretation, and written explanation for Grade 6 science instruction.
