Commensalism is a type of symbiotic relationship in which one species benefits from the presence of another without harming it.

Light pollution is not a type of pollution in the same way that air, water, and soil pollution are. It is a form of environmental degradation caused by excessive artificial light.

Biodegradation is the process by which pollutants are broken down by microorganisms into simpler, less harmful substances.

Oxygen is not a greenhouse gas. Greenhouse gases are gases that trap heat in the atmosphere, causing the planet to warm.

Biomagnification is the process by which pollutants become more concentrated in organisms at higher trophic levels in the food chain.

Fossil fuels are not a type of renewable energy. They are formed from the remains of ancient plants and animals and are a finite resource.

Emission, discharge, and leakage are all terms used to describe the process by which pollutants are released into the environment.

Eutrophication is not a type of air pollution. It is a type of water pollution caused by excessive nutrients, such as nitrogen and phosphorus.

Detoxification is the process by which pollutants are transformed into less harmful substances.

Thermal pollution is not a type of water pollution. It is a type of air pollution caused by the release of heat into the atmosphere.

Mutualism is a type of symbiotic relationship in which both species benefit from each other.

Erosion is not a type of soil pollution. It is a natural process that occurs when soil is worn away by wind, water, or other forces.

Dispersion, diffusion, and advection are all terms used to describe the process by which pollutants are transported from one place to another.

Nuclear energy is not a type of renewable energy. It is a type of non-renewable energy that is generated by the fission or fusion of atomic nuclei.

Bioremediation, phytoremediation, and mycoremediation are all terms used to describe the process by which pollutants are removed from the environment by natural processes.
