This template gives you a general idea of the layout of your page. You are not completely restricted to this format, so feel free to try out different things. I'll give you feedback as you work on your pages. Make sure to copy the "code" of this page to your own page before editing. -Prof Kent

In the introduction, briefly describe the habitat that is the topic of this page. Introduce the habitat, its ecological significance, and the importance of microorganisms in this environment. (What processes do they carry out? What functions do they perform?)

Physical environment

The formation of the karst topography begins with the "carbon dioxide cascade. Rainfall absorbs CO2 from the atmosphere during droplet formation, while it falls as precipitation, or as it moves through the soil horizons. This forms carbonic acid (H2CO3).

H2O + CO2= H2CO3


Describe the physical and chemical characteristics of the environment, using as many sections/subsections as you require. Look at other topics available in MicrobeWiki. Which involve processes similar to yours? Create links where relevant.
