Disturbance, Interactions & Ecosystem Change — Drills · Grade 10 Science
Chapter: Ecosystems & Conservation DecisionsWhat these drills covers
By the end of Disturbance, Interactions & Ecosystem Change you should be able to:
- I can explain how changing one population can affect several others.
- I can distinguish resistance, recovery, and a changing ecosystem baseline.
2 questions, written answer, each with a worked explanation.
Vocabulary used: disturbance, resistance, succession.
Problem 1
Why should a prediction after disturbance include uncertainty?
Answer and explanation
Resources, dispersal, interactions, climate, and later disturbances can change the response.
Problem 2
Design one measurable indicator of ecosystem recovery and state its limit.
Answer and explanation
Track native plant cover across years and matched sites; it does not alone measure species diversity, soil function, or all populations.
