TRY IT Distinguish Elements Explain why there are more substances on Earth than are listed on the periodic table of elements. ​

The periodic table of elements includes only elements.

Explanation:

All the materials on Earth are made up of the same elements, which can be found on the periodic table. These elements combine to form compounds, or mixtures such as water, a compound of hydrogen and oxygen, or air, which is a mixture of nitrogen, oxygen, carbon dioxide (a compound!) and many other gases, even water vapor. It is the combination of these elements in different ways that gives us so many different substances. Hope this helps!

Explanation:

Elements are pure substances with only one type of atom.

The substances on Earth are created when two or more elements are combined.

Because elements can combine to form compounds, more substances can be created on Earth.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
