# Bio Farm

**Number of plots**: 250 

**Income Model**: Resource Purchase & Refill

Special bio-farms have been constructed to serve as a sustainable source of food and oxygen on Carda Station. While in the colonies, you don’t need to worry about oxygen levels. Exploring the outer worlds however is a different experience. We are developing some survival/resource management aspects as part of Exploration and one of those resources will be oxygen. For those long excursions off colony, you’d need a tank of O2 to get you through.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cardastation.com/home/land/colonies/colony-1/bio-farm.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
