Study Notes
Web of Nature
- Organisms, including humans, rely on ecosystems.
- A Japanese proverb states: "When the wind blows, the barrel maker profits" (風が吹けば桶屋が儲かる).
- Ecosystems consist of living and non-living things.
- Ecosystem function relies on photosynthesis.
- Photosynthesis uses carbon dioxide (CO2) and water (H2O) to produce oxygen (O2) and glucose.
- Photosynthesis allows plants to grow.
- Photosynthesis is vital for the ecosystem.
- The carbon cycle occurs in nature.
- The nitrogen cycle is part of natural processes.
Ecosystem Variety
- Ecosystems come in global and local scales.
- Local examples may include a sloth's back.
- Globally, ecosystems involve large environments.
Food Chain/Web
- Food chains track the flow of energy through living organisms.
- Organisms can act as producers (plants) or consumers (animals).
- Consumers can be carnivores (meat eaters), herbivores (plant eaters), omnivores (both eaters)
- Food webs show interconnected relationships within ecosystems.
Decomposers
- Decomposers are organisms that break down organic materials into inorganic compounds.
- Soil organisms decompose organic material.
- Examples of decomposers include fungi, bacteria, and some soil animals.
- Scavengers are a type of decomposer.
- Decomposers recycle nutrients in ecosystems.
Photosynthesis
- Photosynthesis in plants results in oxygen as a byproduct.
- Plants use carbon in photosynthesis.
- Photosynthesis converts carbon into plant material.
Carbon Cycle
- Summary of the carbon cycle in ecosystems.
- Carbon moves between living and non-living matter.
- Photosynthetic organisms play a crucial role in the carbon cycle.
- Consumers take in carbon-containing matter from plants.
- Decomposers contribute to the carbon cycle, breaking down organic matter.
- Storage of carbon also occurs in different forms, such as in forests.
- Conversion of organic matter into carbon-based fuels, such as coal, is one natural process.
Nitrogen Cycle
- Summarizing the nitrogen cycle process.
- Atmospheric nitrogen is converted to usable forms.
- Nitrogen-fixing bacteria convert atmospheric nitrogen to a usable form for plants.
- Plants use this fixed nitrogen to make proteins, other compounds used by ecosystems.
- In the cycle, decomposers are essential for transforming nitrogen-containing organic compounds into simpler forms for reuse.
- Industrial processes like the Haber-Bosch process play a large role converting nitrogen gases into ammonia used in fertilizer production.
Problems caused by Excess Nutrients
- Algae blooms and plankton blooms are problems caused by excess nutrients.
- Excess nutrients can harm ecosystems.
Planetary Boundaries
- Limits to human activities on ecosystems.
- Specific examples of boundaries relate to concentrations of CO2 and nutrient flows that negatively affect processes in the ecosystem.
Conclusion
- Photosynthetic organisms are central to ecosystems.
- Nutrients and carbon are important in maintaining stable ecosystems.
