Which of the following best describes uranium (a type of nuclear fuel)? a.) renewable only b.) nonrenewable only c.) recyclable and renewable d.) recyclable and nonrenewable

Answer is B.) nonrenewable only

Nuclear energy is usually considered as renewable energy.  But the material which used in the nuclear power plants is non-renewable resource. A rare type of a uranium which is U-235 is used nuclear power plants. This element is a non-renewable resource. Nuclear energy from uranium is released through a process called nuclear fission. In the nuclear fission the nucleus of a uranium atom splits to give energy.

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.
