Microbiology Semester 2 Week 3

           Assalamualaikum and hi everyone... how are you all? I hope everyone will be fine as well... On Tuesday, before the microbiology class Dr Wan asked us to do some quizzes about the principle in ecology in our open learning MOOC page. In microbiology, Dr Wan was taught us more about the principle of ecology. Basically, Ecology is the systematic study of organisms and their interactions with the environment and reveals the relationships between living and nonliving parts of the environment. Five types of hierarchy of ecology which are species, population, communities, ecosystems and biospheres. Homeostasis is the dynamic balance of processes, materials and organisms in the ecosystem and biosphere. Processes such as balance of photosynthesis and metabolism. Materials such as nutrient and waste product. Organisms such as predators and preys. Energy flow through the ecosystems is energy itself does not recycle, energy only recycle in the form of C-C bonds (C-C bond contain energy), conversion of energy: never 100% efficient, Ultimate fate of energy: lost as heat and Ultimate source of energy which is SUN Points. Roles of the microbe in the ecosystems is oxygen producer (half of the oxygen on earth is produced by trees in the rainforest; the other half by blue-green algae in the ocean), fix nitrogen in the atmosphere into usable form,  recyclers of dead materials, source of food in food chain and contribute to evolution to remove weaker species through infections.

       Factors that may affect the stability of the ecosystems is increase in the frequency of natural or unnatural disturbances , abrupt change in species diversity and change in the rate of nutrient and energy consumption. Approaches to effective Ecosystem Management is stakeholders, adaptive management, natural resource management, strategic management and landscape level conservation.

Dr Wan was postponed our class on Friday to another day. So, Friday no class but Dr Wan asked us to search more about adaptation of the eukaryotes so as usual my group to find the adaptation of the fungi.
