Population_model - Wikiparency

# Population model ## MicroSim spec - **Recommended sim type:** predator-prey dynamics - **Microsimmability score:** 84/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Birth rate` - `Death rate` - `Carrying capacity` ### What animates A modeled population grows, crashes, or stabilizes as birth, death, and capacity change. ### Learning objective Show how birth, death, and capacity shape a population over time. ## Links (Wikipedia order)  `7_Billion_Actions` · `Alfred_J._Lotka` · `Antinatalism` ·

applied to the study of [[Population_dynamics|population dynamics]]. ## 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: Population 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 · Wikipedia: [Population
