Which best describes a role of animals in the water cycle? a. they water vapor condense when they produce waste. b. they water vapor condense when they inhale. c. they release water vapor through transpiration. d. they release water vapor when they exhale.

d. They release water vapor when they exhale.

Explanation:

Water cycle is also known as the hydrologic cycle. water cycle is the circulation of water in the earth atmosphere system. Water cycle describes the continuous movement of water on the earth, above the earth and below the earth.

Water move through the earth-atmosphere system by different process like condensation, evaporation, transpiration, infiltration and many more process. Water evaporates to the atmosphere through surface water like oceans, lake,sea etc by process of evaporation.

Animals contributes to the process of water cycles by breathing and urination. Animals exhales  more water vapor than they inhale and this contribute to the water cycle. They also contribute to the water cycle by urinating.  

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
