fragrance means smell & flowers often have a sweet smell to attract pollinators ->  flowers use fragrance to attract pollinators  flowers use fragrance to attract pollinators & increasing the amount of something used by an organism to perform a process increases that organism's ability to perform that process ->  as the amount of fragrance of a flower increases , the number of pollinators it will attract increases  as the amount of fragrance of a flower increases , the number of pollinators it will attract increases & as the size of a flower increases , the number of pollinators it will attract increases ->  as the size and amount of fragrance of a flower increases, the number of pollinators it will attract increases  pollination requires pollinators & plant reproduction requires pollination ->  plant reproduction requires pollinators  increasing the amount of something used by an organism to perform a process increases that organism's ability to perform that process & a plant is a kind of organism ->  increasing the amount of something used by a plant to perform a process increases that plant's ability to perform that process  plant reproduction requires pollinators & increasing the amount of something used by a plant to perform a process increases that plant's ability to perform that process ->  as the number of pollinators attracted to  a plant increases , the ability of that plant to reproduce will increase  increasing an organism's ability to reproduce has a positive impact on that organism & a plant is a kind of organism ->  increasing a plant's ability to reproduce has a positive impact on that plant  as the number of pollinators attracted to  a plant increases , the ability of that plant to reproduce will increase & increasing a plant's ability to reproduce has a positive impact on that plant ->  increasing the number of pollinators attracted to a plant has a positive impact on that plant  as the size and amount of fragrance of a flower increases, the number of pollinators it will attract increases & increasing the number of pollinators attracted to a plant has a positive impact on that plant ->  increasing the size and amount of fragrance of a flower has a positive impact on that flower by increasing the number of pollinators it will attract  increasing the size and amount of fragrance of a flower has a positive impact on that flower by increasing the number of pollinators it will attract & a bee is a pollinating animal -> increasing the size and amount of fragrance of a flower has a positive impact on that flower by increasing the number of bees it will attract
