The energy from the sun is the most responsible for the water cycles. Think about it: Without the energy from the sun, water would not be able to evaporate (which is the first process in the water cycle), so it wouldn't be able to transition to the next process.
The answer is D. Contain chlorophyll
Carbon dioxide (chemical formula <span>CO2</span>) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.<span />
