Cars are a big source of air pollution. The smoke out of car mufflers are the main source of the pollution. This is why many car companies are starting to make more electrical cars because they release less exhaust fumes.

The correct answer is (a) driving.

The pressence of undesirable substances in air is called as air pollution. There are many human activities that contribute to air pollution. The biggest contributor is driving. The pollutants that comes out of the car are carbon dioxide, carbon monoxide. They also release hydrocarbon and nitrogen oxides which when combines in sunlight becomes ozone. Air pollutants emitted by cars and other automobiles increases the level of harmful gases which to severe health problems such as heart disease, asthma, irritation in eyes.

Wetlands are important ecosystems for many reasons. Select all that apply.

vazorg [7]

A, B, & D.

Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem.

Explanation:

Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera. The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water.

Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.
