Some of the carbon atoms in the glucose exit the leaf as carbon dioxide during respiration while other carbon atoms are used to make important parts of the plant, such as additional leaves or wood. Carbon atoms that remain in leaves will either fall off (during plant senescence) or become a meal for an animal. Hope this helps
        
                    
             
        
        
        
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring). 
which class question is this?
