Study Notes
Eutrophication and Water Pollution
- Eutrophication is a process where excess nutrients, such as nitrogen and phosphorus, accumulate in water bodies, promoting excessive plant growth and depleting oxygen levels, leading to aquatic life death.
Biochemical Oxygen Demand (BOD)
- Biochemical oxygen demand (BOD) measures the amount of dissolved oxygen required by microorganisms to break down organic matter in water, indicating water quality.
Photochemical Smog
- The main components of photochemical smog are nitrogen oxides, volatile organic compounds, and ozone, which react in the presence of sunlight to form a toxic mixture of air pollutants.
Deforestation
- Deforestation generally decreases biodiversity, as it leads to the loss of habitats, extinction of species, and disruption of ecosystem services.
Alpha Diversity
- Alpha diversity refers to the variety of different species present within a specific geographic area or ecosystem, highlighting the richness of species in a local community.
