the branch of biology dealing with the relations and interactions between organisms and their environment, the physicals and biological factors affecting them or influenced their distribution and abundance, and understanding the mechanisms involved in biological diversity.
Hierarchy of ecology:
1. Species/organism - organisms with common genetic makeup, behavior, physical characteristics
2. Population - a group of individuals belonging to the same species inhabiting a particular geographical area
3. Community - all populations of different species inhabiting a particular area
4. Ecosystem - a relationship between a communities (biotic composition) and their physical environment (Abiotic composition)
5. Biosphere - all ecosystem on Earth
5. Biosphere - all ecosystem on Earth
Development of microbial communities:
- r strategy: dominates environment rich/temporary rich in resources
- K strategy: tend to be successful in resource-limited situations
- preemptive colonization: to discourage further succession by other organisms
- autogenic succession: microorganisms modify the habitat and permits new populations to develope
- allogenic successsion: when habitat is altered by environmental factors
- homeostasis: dynamic balance of process, materials and organisms in the ecosystem and biosphere
