Biofilm is defined as one or more types of microorganisms collectively grow in different places. Organisms that form the biofilm include protests, fungi, and bacteria.
Dental plaque is an example of a biofilm. It is a known buildup of slimy bacteria that forms on the teeth surface. Biofilm can grow on different surfaces such as animal tissues, plant tissues, minerals, metal, etc.
The zonation of flora and fauna along an altitudinal transect similar to that found along latitudinal transects is an expression of the the life zone concept.
<h3>What is life zone concept?</h3>
- C. Hart Merriam created the term "life zone" in 1889 to refer to regions with comparable plant and animal groups. Depending on height, location, and latitude, the climate and ecology of many places on the planet naturally divide into life zones.
- Altitudinal zonation is the term for the generally substantial dependence on elevation: the average temperature of an area falls as the height increases.
- The US has thirty-eight life zones, including one boreal, twelve cool temperate, twenty warm temperate, four subtropical, and one tropical (34% of the world's life zones and 85% of the temperate ones).
