Principles of ecology.This chapter has a lot of definition need to be know. Abiotic factor are non living part of enviroments such as temperature water sunlight wind rocks and soil periodic disturbances https://classconnection.s3.amazonaws.com/665/flashcards/2470665/png/abiotic_factor1362439889644.png Homeostasis is dynamic balance of processes,materials and organisms in the ecosytem and biosphere Microbes also have roles in the ecosystems oxygen producer. Half of oxygen produce by blue-green algae in the ocean.I wonder how this algae can produce oxygen?Does it has same process as in tree? fix nitrogen in the atmosphere into usable form recyclers of dead materials source in food chain contribution to evolution:remove weaker species through infections What I have learn: -Ecology is the systematci study of organisms and their interactions with enviroment -Example of decomposer is fungi -blue-green algae produce oxygen

The first topic that I learn in BMY 3102 is Nomenclature and classification of microorganism.In this topic I learn about how to correctly write name for microbe.I also learn how the process of naming new bacteria which from my view it is little bit complicated and take a long time to name a new bacteria.When studying about this I have been expose to the Bergey Manual. I also have been exposed about Bergey Manual.Which I have been ask to go library to find it and take picture of it.It has two type that are systematic and determinative. Next, I learn about classification system that are phenetic, phylogenetic and genotypic.Phenetic is about numerical taxonomy which related to dendogram, Phylogenetic is based on phylogenetic tree lastly,genotypic is more to other molecular methods.Under all of these system many methods are used.Some of them combine many methods to classify the microorganism.All these method can be divide under two group that are classical and molecular method.I was ...
relate Microbial Ecology to other microbiology courses have covered and apply the knowledge in the future
In previous subject I learn their characteristics and uses. When I am studying Microbial ecology I get to know more about the place that I learn their characteristics and uses. I also study lab of microbiology with the knowledge from both course I should be able to know how to find and isolate microbes. Different microbes stay in different places. Different microbes require different way to isolate them. For the future application, I think to solve a problems using microbes, the microbes that will solve the problems need to be find in the problems occur. For example, bacteria that involve in bio remediation usually live and isolated in polluted area since there are able to withstands the pollutants.
