... On Earth, oxygen is the most common element. If one were to take the planet and divide it into different elements, they would end up with 32% iron, 30% oxygen, 15% silicon, 14% magnesium, 3% sulfur, 2% nickel as well as calcium, aluminum and various trace elements. More than 92 percent of the universe is hydrogen. All living things are made up of just a few elements. Most of the rest is helium. The answer to your question is D. 2. Elements make up everything around us including the trees of a forest, your pets, and even YOU! Carbon is so abundant in living things when oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot … In living things (plants, animals, people) the six most abundant elements are carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. In the human body, for example, these elements, together with carbon, make up about 96% of the body’s weight. Carbon is the 4th most abundant element in the Universe today. Three other commonly found elements, oxygen, hydrogen, and nitrogen, are also important in the structure and function of living things. On earth, you can find hydrogen in the form of water or organic compounds, such as carbohydrates. Since 1900, carbon dioxide has increased mostly because of human activity. They make up all lifeforms on Earth. Every living thing in the planet lives on the Earth’s crust, which is the outermost layer. *Response times vary by subject and question complexity. Other elements can be found in biomolecules, but these six are by far the most common. This chemical element, which symbol is H, is the lightest element. The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth. The elements that are most abundant in living organisms are oxygen, nitrogen, carbon, hydrogen, sulfur, and phosphorus. Create a chart like on the bottom of page 175 and list the elements that are in Earth, Earth Atmosphere, Earth Oceans, and Living Things. CHON is a mnemonic acronym for the four most common elements in living organisms: carbon, hydrogen, oxygen, and nitrogen.. If you looked at living things with a microscope, you would see that all life is made up of small compartments called cells. 1. For example, all living things have a great deal of water. All of these elements … Very small life forms, such as bacteria, have only one cell, while large animals have millions. Oxygen and hydrogen make water. As you can see from the long-term carbon cycle, carbon takes up various forms such as carbon dioxide (CO 2), methane (CH 4) and glucose (C 6 H 12 O 6). There are 92 naturally occurring elements; only 17 of them make up 99.5% of the earth's crust (including oceans and atmosphere). Oxygen and hydrogen are highly important in body processes that obtain and use energy from food. The universe is dominated by the elements hydrogen (83%) and helium (16%) 1. Other major elements found in living things are hydrogen. Beyond Earth the most common element is hydrogen. Carbon is the most important element for building molecules essential for living things. The Crust… While carbon is the fourth most abundant element in the universe, hydrogen is on top of the list. The CHNOPS elements - the six most common elements in living organisms. Median response time is 34 minutes and may be longer for new subjects. You may have heard the kind of life on Earth (in other words, the only kind we know for certain exists anywhere) referred to as "carbon-based life," and with good reason. Read pages 174 - 175. But and nitrogen, oxygen, hydrogen, and phosphorus are indispensable to living things as well, and a host of other elements are in the mix to lesser degrees.
