Study Notes
Microorganisms and Ecosystems
- Microorganisms typically found in water bodies and soil play a crucial role in nutrient cycling, providing essential nutrients for the growth of other organisms.
- These microorganisms include bacteria, fungi, and algae, which contribute to the overall health of aquatic and terrestrial ecosystems.
Importance in the Atmosphere
- Microorganisms generate oxygen as a byproduct of photosynthesis, which is vital for the survival of aerobic organisms.
- This process significantly contributes to atmospheric oxygen levels and supports life on Earth.
Nutrient Fixation
- Microorganisms, especially certain bacteria, fix nitrogen in the soil, which is essential for plant growth.
- This biological nitrogen fixation transforms atmospheric nitrogen into forms that plants can utilize to synthesize proteins and DNA.
Diversity of Microorganisms
- It is estimated that there are approximately 1 trillion different species of microorganisms on Earth, highlighting the immense diversity of microbial life.
- Many of these species remain undiscovered and play various roles in ecosystems.
Fungi and Associations
- Fungi, a major group of microorganisms, are often associated with mushrooms.
- They play a significant role in decomposition and nutrient cycling, forming symbiotic relationships with plants through mycorrhizal associations.
