No it isnt a rational nu7mber.
It is (D) Carbon dioxide.
in lactic acid=C6H12O6 to produce 2C3H6O3+Energy.
in alcoholic fermentation=C6H12O6 to produce 2C2H5OH+2CO2.
therefore all of them produce (D) Carbon dioxide.
Predation
It can be explained in that way or also called Predatory/prey relationships.
Parasitism is when one is benefited and the other harmed (ie leech and human)
Commensalism is when one is benefited and the other not affected (Tree frog and rainforest tree)
Mutualism is when both are benefited (Bee eats honey and Flower is pollinated).
