Study Notes
Bacterial Structure and Behavior
- Bacterial structure is simple but their behavior is complex.
- Bacteria, as a group, exhibit extensive metabolic diversity.
Bacterial Nutrition
- Some bacteria are autotrophs, producing their own food from inorganic compounds.
- This includes photosynthesis and chemosynthesis.
- The majority of bacteria are heterotrophs, relying on other organisms or dead organic matter for food.
Bacterial Habitats
- Some bacteria thrive in extreme environments, such as highly saline areas (halophiles) or hot springs (thermoacidophiles).
- Bacteria in marshy areas (methanogens) are also notable.
Archaebacteria
- Archaebacteria differ from other bacteria in their cell wall structure.
- This difference allows them to survive in extreme conditions.
Methanogens
- Methanogens are a type of archaebacteria present in the digestive tracts of ruminant animals.
- They produce biogas from animal dung.
