Th...This page discusses how DDT accumulates in organisms through biomagnification across four trophic levels, resulting in higher toxin concentrations in top-level consumers such as ospreys and eagles. The slow metabolism and excretion of DDT lead to severe ecological consequences, including population declines in affected carnivores, as trace amounts in primary producers like plankton become exponentially concentrated as they ascend the food chain.

It explains Biochemical Oxygen Demand (BOD) related to organic matter, emphasizing the importance of keeping BOD below 1 for drinking water. The sewage treatment process includes primary, secondary, and optional tertiary treatments to reduce BOD and nutrients.

When incoming energy from the sun is absorbed, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When energy is released from Earth into space, the planet cools. Many factors, both natural and human, can cause changes in Earth’s energy balance.

The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) resulting from fossil fuel combustion.
