Ecosystem stability and mathematical models are the focus of this Grade 11 Science worksheet, giving students practice interpreting how species interactions, feedbacks, disturbances, migration, and resources shape ecosystem dynamics and resilience.

What students explore

Students examine how different ecosystem models represent change over time and compare network models, differential-equation models, and agent-based frameworks. The lesson develops vocabulary and reasoning around interaction strengths, resource availability, migration rates, disturbance regimes, negative feedbacks, stability, equilibrium, and resilience.

The reading passage connects conceptual diagrams with mathematical and computational approaches. Students consider how differential equations can represent birth, death, predation, and competition; how networks use nodes and edges to represent species interactions; and how agent-based models use individual rules for movement, hunting, and reproduction to produce population-level patterns.

Student Tasks

The worksheet moves from guided reasoning into application. Students complete a dialogue, matching activity, cloze passage, labeled diagram, and reading passage, followed by multiple-choice questions, true-or-false statements, short-answer responses, and an extended-response task. The final response asks students to select a model type and explain how parameters and feedbacks can be used to evaluate resilience after habitat disturbance.

What You Receive

• Worksheet focused on conceptual and mathematical ecosystem models
• Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Use

Use this resource for direct instruction, independent practice, review, or written assessment within an ecosystems unit. The combination of reading, model interpretation, selected-response questions, and extended explanation gives students opportunities to connect ecosystem vocabulary with model-based reasoning rather than treating stability and resilience as isolated definitions.

Why it earns a place in your lesson sequence: students work with the actual model components scientists use to investigate ecosystem behavior, including interaction strengths, migration, resource availability, and disturbance regimes. The resource also asks students to distinguish stability from resilience and justify expected outcomes when model parameters change.

Designed for Grade 11 NGSS Science instruction on ecosystems, interactions, energy, and dynamics.
