One example of irradiation solving a societal problem might be the way
in which it is able to prevent diseases in food. Using small amount of
radiation, the bacteria and insects that would otherwise be carrying
harmful bacteria can be killed. This will solve a societal problem, in
that food wastage and illness due to food poisoning in poverty-stricken
areas are massive problems faced in our society.
The carbon is among the most abundant element found in the living organisms. The carbon enters the food web through the producers via the process by which they make their food, which is known as photosynthesis. The plants during the process of photosynthesis, take in carbondioxide, water and capture the sunlight to make ATP. The carbon from all these elements enters the producers and then is passed on from one trophic level to another.
Hence, the blanks can be filled with 'producers, and photosynthesis'.
