Disturbance — Science definition
Defined in 2 courses:
- An event disrupting a community — fire, flood, drought, felling; many communities are shaped by regular disturbance rather than harmed by it. (Life Science & Scientific Inquiry)
- An event that changes ecosystem conditions or structure. (Life Science: Biology)
Where it is taught
- Interactions & Ecosystem Change — Ecological Evidence & Environmental Design, Life Science & Scientific Inquiry, Grade 7
- Disturbance, Interactions & Ecosystem Change — Ecosystems & Conservation Decisions, Life Science: Biology, Grade 10
In use
A disturbance is an event that disrupts a community — a fire, a flood, a storm, a drought, a felling.
Interactions & Ecosystem Change
A disturbance can change resources, populations, and conditions.

Questions using disturbance
Problem 1
Answer and explanation
It has low resistance for this disturbance/output but relatively rapid recovery over the stated interval. Output recovery alone does not establish restored species composition or every ecological function.
It has low resistance for this disturbance/output but relatively rapid recovery over the stated interval. Output recovery alone does not establish restored species composition or every ecological function.
Response criteria
- Use the stated measurements or conditions, with correct units.
- Connect the result to the biological mechanism or evidence relationship.
- Identify the assumption, model limit or further evidence requested.
Problem 2

Problem 3
Answer and explanation
Resources, dispersal, interactions, climate, and later disturbances can change the response.
