    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.
