Study Notes
Eutrophication
- Eutrophication is a process where a body of water becomes enriched with excess nutrients, leading to an explosion of algal growth, deoxygenation, and harm to aquatic life.
Biochemical Oxygen Demand (BOD)
- BOD measures the amount of oxygen required by microorganisms to break down organic matter in water, indicating the level of water pollution.
Photochemical Smog
- Ozone (O3) is a main component of photochemical smog, which is a type of air pollution formed when ultraviolet light reacts with nitrogen oxides, volatile organic compounds, and other pollutants.
Deforestation
- Deforestation typically leads to a decrease in rainfall, as the loss of forest cover disrupts the water cycle, reduces evapotranspiration, and alters the local climate.
Alpha Diversity
- Alpha diversity refers to the variety of different species present within a single ecosystem or community, measuring the richness and diversity of species within a specific area.
