# Ecosystem model ## MicroSim spec - **Recommended sim type:** predator-prey dynamics - **Microsimmability score:** 82/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Prey growth` - `Predation rate` - `Predator efficiency` ### What animates Coupled species populations rise and fall as the [[Ecosystem|ecosystem]]'s interaction rates change. ### Learning objective Show how species interactions drive ecosystem dynamics. ## Links (Wikipedia order) <!-- injected from

Relation: subfield of systems thinking. ## Concept summary An ecosystem model is an abstract, usually mathematical, representation of an ecological [[System|system]] (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system. ## Build checklist - [ ] Claim it: set `status: in-progress` + `lease` + `leased_at` - [ ] Write the child page explaining the concept (tie it back to systems thinking) - [ ] Finalize parameter ranges and defaults - [ ] Implement the p5.js sketch (drawing + control regions) - [ ] Add caption + the learning objective on the page - [ ] Set `status: done` ## p5.js sketch ```javascript // MicroSim: Ecosystem model let controls = {}; function setup() { // createCanvas(...); create sliders for the parameters above. } function draw() { // background(...); read controls; render predator-prey dynamics; respond live. } ``` --- Back to Systems Thinking ·
