C) a system is a set of parts that function together as a whole
Answer:
The use of rocks and minerals includes building material, cosmetics, cars, roads, and appliances.
Explanation:
According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. The use for the water in the world is for household drinking water. The ocean stores about 97 percent of the Earth's water; the remaining three percent is stored in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is stored in the ocean.

D.Elements continuously cycle between the physical environment and living organisms.
Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>
