What is this retardation?
Nitrogen is part of the chlorophyll molecule. Plants create chlorophyll and use it to combine water, CO2, and light to produce energy in the form of sugar and oxygen (which we breath). Some animals eat plants. Other animals eat animals. Other animals eat both. Other animals still eat fungi. My dog eats cat crap if left unattended. Plants produce protein. So do animals. Humans are animals.
Yeah, what the science guy here says!
