The tiny carbon cycle is piggybacking on the huge water cycle, not driving it. The carbon cycle is the dominant energy source for ordinary stars of mass greater than about 1.5 times the mass of the Sun.
Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant’s leaves. Animals and plants are connected to each other by the oxygen-carbon dioxide cycle.
The correct answer is option C – Oxygen cycles through the processes of photosynthesis and cellular respiration. While water is broken down to form oxygen during photosynthesis by the water plants, in cellular respiration oxygen is combined with hydrogen to form water.
1. Carbon dioxide consists of carbon and oxygen. 2. He is a carbon of his father.
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms.
NARRATOR: Carbon and oxygen are two elements that are essential to life. They are naturally present in the atmosphere in the form of carbon dioxide and gaseous oxygen. Because they’re always circulating between the soil, the air, and the water, living matter’s constantly renewed.
1 : a nonmetallic chemical element with atomic number 6 that readily forms compounds with many other elements and is a constituent of organic compounds in all known living tissues — see Chemical Elements Table. 2 : a carbon rod used in an arc lamp. 3a : a sheet of carbon paper.
Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6. Carbon’s abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables this element to serve as a common element of all known life.
