Study Notes
Environmental Concepts
- Eutrophication: A process where a body of water becomes enriched with excess nutrients, leading to an overgrowth of algae, depletion of oxygen, and subsequent harm to aquatic life.
Water Quality Indicators
- Biochemical Oxygen Demand (BOD): A measure of the amount of oxygen required by microorganisms to break down organic matter in water, indicating the level of water pollution.
Air Pollution
- Photochemical Smog: A type of air pollution caused by the reaction of sunlight, nitrogen oxides, and volatile organic compounds, resulting in a mixture of harmful pollutants, including ozone, particulate matter, and nitric acid.
Ecology and Biodiversity
- Alpha Diversity: A measure of the variety of species within a specific ecosystem or habitat, reflecting the richness and evenness of species composition.
Forest Ecology
- Deforestation: The clearance of forests, leading to a decrease in biodiversity, loss of habitat, and disruptions to ecosystem processes, ultimately decreasing ecosystem resilience.
