APES Final Exam Review (2025)

Front

What is acid deposition?

Back

Acid deposition refers to the falling of acids from the atmosphere to the Earth's surface, primarily in the form of rain, snow, or dust. It is often caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from industrial processes and vehicles.

Front

What are sustainable practices?

Back

Sustainable practices are methods of using resources in a way that meets current needs without compromising the ability of future generations to meet their own needs. Examples include reducing waste, conserving water, using renewable energy, and promoting fair trade.

Front

What are density-dependent factors?

Back

Density-dependent factors are variables that affect a population's growth in relation to its size. These include food availability, predation, disease, and competition.

Front

What are density-independent factors?

Back

Density-independent factors are environmental factors that affect population size regardless of the population's density. Examples include natural disasters, climate changes, and human activities.

Front

What is the role of bacteria in secondary sewage treatment?

Back

Bacteria in secondary sewage treatment break down organic matter in wastewater, further purifying it after primary treatment by decomposing waste materials.

Front

What is the significance of being downwind from a coal-fired power plant?

Back

Being downwind from a coal-fired power plant increases the likelihood of experiencing acid deposition due to the release of sulfur dioxide and nitrogen oxides, which can lead to environmental and health issues.

Front

What is the impact of natural disasters on populations?

Back

Natural disasters are density-independent factors that can drastically reduce population sizes regardless of the population's density, leading to sudden changes in ecosystem dynamics.

Front

What is the difference between competition and predation?

Back

Competition occurs when individuals or species vie for the same resources, while predation involves one organism (the predator) feeding on another (the prey), impacting population dynamics.

Front

How does water conservation contribute to sustainability?

Back

Water conservation helps to ensure that water resources are available for future generations, reduces the energy required for water treatment and distribution, and protects ecosystems.

Front

What is the importance of renewable energy?

Back

Renewable energy sources, such as solar, wind, and hydroelectric power, are crucial for reducing greenhouse gas emissions, decreasing reliance on fossil fuels, and promoting environmental sustainability.
