Several states encourage the use of bicycles, pedestrian paths, and public transportation. These efforts are advantageous in :

• • increasing levels of nitrogen that protect against atmospheric temperature change

• • reducing emissions of ultraviolet radiation that cause the greenhouse effect

• • increasing levels of oxygen that sustain microbial and other forms of life

• • reducing emission of greenhouse gases that cause global warming

Which of the following best describes photosynthesis?

• • The process of sunlight causing water to evaporate, which then condenses and eventually precipitation occurs.

• • The process of fish and mammals utilizing sunlight, carbon dioxide, nitrates and water and converting these factors into oxygen and glucose.

• • The process of plants and trees utilizing sunlight, carbon dioxide, nitrates and water and converting these factors into oxygen and glucose.

• • The process of breaking down dead organic matter.

A log has decayed in a forest. The log is considered biotic because it —

• • was once a living organism

• • became a habitat for many insects

• • stored rainwater for birds to drink

• • occupied space in the forest

Although most of Earth's atmosphere is made up of nitrogen, fertilizers containing nitrates are often added to the soil to promote plant growth because

• • Falling rain cannot maintain dissolved nitrogen compounds

• • Plants cannot process atmospheric nitrogen

• Soil minerals cannot retain nitrates

• • atmospheric nitrogen cannot be absorbed by ground water
