Study Notes
Microbes Overview
- Types of microbes include bacteria, viruses, fungi, archaea, and protozoa. Larger organisms like plants and animals are not classified as microbes.
- Microbes play crucial roles in ecosystems, biotechnology, and medicine.
Presence of Microbes
- Microbes are ubiquitous; they are found in diverse environments such as soil, water, air, and within and on the surfaces of other living organisms.
- They occupy extreme habitats including hot springs, deep-sea vents, and Antarctic ice.
Microbial Existence
- Microbes can exist in aerophilic, anoxic, or anaerobic conditions, adapting to oxygen levels of their environments.
- They are able to withstand extreme temperatures, pH levels, and salinities, showcasing their resilience.
Microbial Kingdoms
- Major kingdoms containing microorganisms include Bacteria, Archaea, and Fungi, with some protozoa classified under the Protista kingdom.
- Each kingdom displays distinct cellular organization, reproduction methods, and metabolic pathways.
Biological System Components
- Major components of biological systems on Earth include microbes, which contribute to nutrient cycling, energy flow, and ecosystem balance.
- Microbes form the foundation of food webs and are essential for the decomposition process, supporting life on Earth.
