such as plants, trees, grasses and soil. These organisms naturally absorb carbon as part of their life cycle, converting it into cellulose which helps them to grow and develop. In return, they release oxygen into the atmosphere, which is then inhaled by humans. The whole ...
the seventh element of the periodic table between carbon and oxygen is nitrogen. it’s an important part of amino acids. around eighty per cent of the earth’s atmosphere comprises nitrogen gas. it has no colour, mostly diatomic non-metal gas which is odourless and colourless in nature. ...
What is the carbon cycle? Carbon is the basis of all life on earth – it is a key ingredient in almost everything on the planet. As the earth has a closed atmosphere, there has always been the same amount of carbon on the earth, but it is in a constant state of change, transitioni...
(H2) and oxygen (O2) using electricity. This process, called water electrolysis, is a promising option for carbon-free hydrogen production since the electricity can be sourced from nuclear or renewable energy, such as wind and solar. Scientists and engineers are working to improve and lower the...
Carbon is responsible for making food and oxygen, which is a good thing but too much carbon can cause global warming. It wouldn't be so bad if there were so many trees being cut down. Byanon158641— On Mar 08, 2011 No one is being wise. i think we shouldn't be paying for Carbon...
Carbon is the sixth element in the Periodic Table of Elements. It has an atomic number of six. It contains four valence electrons located at the 2s and 2p orbitals. It usually shares this four electrons with other atoms to form four covalent bonds....
What are two processes that use oxygen? What is the main component of the biological pump? What is the role of photosynthesis and cellular respiration in the carbon cycle? What are the 3 main functions of roots? What is the main mechanism by which gases move from the alveoli into the bloo...
