Ecology of
Microorganisms
- ECOLOGY is the
scientific study of the
interaction between
organism and their
enviroment
- Oikos = a place to live
Logos = to study
- Ecological
Levels
1.Organism
2.Population
3.Community
4.Ecosystem
- Population- a group of individuals in a
particular geographic area that belong
to the same species
- Community - all the
organisms that inhibit a
particular area.
- Ecosystem - dynamic interaction between plants,
animal, and microorganisms and their
environment working together as a functional unit
- BIOSPHERE
- * Biggest ecosystem
*Consist abiotic(non-living
component) and
biotic(living component)
- MICROBIAL ECOLOGY - the
study of interaction between
microorganism and their
environment (Chmcl, Physical,
Biological environments)
- Characteristics Of
Microorganisms
Ecology
- 1. The assortment of microorganisms
sp. 2. Dynamic population 3. Adaptation
and Mutation 4. Association of
microorganisms in ecosystem
- THE INTERACTION AND INFLUENCE OF
MICROORGANISM IN THE ECOSYSTEM
An ecosystem consists of all well as all
the abiotic factors with which they
interact.
- ROLES OF MICROBES
*Primary Producers
-synthesis of organic matter
from CO2 and other inorganic
compund -organisms that
carry out primary production
- *Decomposers (often carry out
mineralization) *Food source for other
organisms *Biogeochemical cycling
*Change amounts of materials in
soluble and gaseous form
- Generalities of chemical cycling
*There are two general
categories of biogeochemical
cycles: Global cycle and Local
cycles
- BIOGEOCHEMICAL CYCLE -This type of cycle of
atoms between living and non-livings is
known as a biogeochemical cycle -involves
organisms(bio),(geo) & Chemical
- Biogeochemical cycle can diveded into 2 basis group :
1. Nutrient cycle form a sediment in atmosphere and
hydrosphere(sea) 2. Nutrient cycle form a sediment
in the surfaces layer of earth
- General Model of
Nutrient Cycling
- 1. Defines major reservoirs of elements and processes that transfer elements.
2. Most nutrients accumulate in four reservoirs that are defined by two
characteristic: i) If they contain organic or inorganic materials ii) whether or
not materials in them are directly or indirectly available to organisms
