# Limiting factor
## MicroSim spec
- **Recommended sim type:** [[Population_dynamics|population dynamics]]
- **Microsimmability score:** 74/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Resource supply`
- `Demand rate`
- `Carrying capacity`
### What animates
Population or output grows until the scarcest resource caps it at the carrying capacity.
### Learning objective
Identify how a single limiting factor constrains the growth of a system.

> A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. ([Wikipedia](https://en.wikipedia.org/wiki/Limiting_factor))

## Concept summary
A limiting factor is a variable of a [[System|system]] that restricts the growth or continuation of processes within a system, typically through its exhaustion.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems science)
- [ ] 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: Limiting factor
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render population dynamics; respond live.
}
```
