Why is nuclear energy considered non-renewable, yet is is not a fossil fuel?
because it uses uranium for fuel which is not a fossil and has a limited supply.
because it has a risk of radiation poisoning
because it is very expensive to build and operate nuclear power plants
because it does not contribute to global warming by putting out air pollution.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
