Study Notes
Environmental Concepts
- Eutrophication: Excessive nutrient supply in water bodies, leading to an overgrowth of algae and depleting oxygen, harming aquatic life.
- Biochemical Oxygen Demand (BOD): Amount of oxygen consumed by microorganisms to decompose organic matter in water, indicating water quality.
- Photochemical Smog: Air pollution formed when sunlight reacts with nitrogen oxides, volatile organic compounds, and other pollutants, mainly consisting of ozone, particulate matter, and nitrogen dioxide.
- Deforestation: Clearing of forests, generally decreasing biodiversity and carbon sequestration.
- Alpha Diversity: Measure of species diversity within a specific ecosystem or habitat, referring to the variety of species present in a particular area.
