In a classic experiment, John Teal studied the flow of energy through the producers, consumers, and detritivores in a salt marsh. Teal measured the amount of solar radiation entering a salt marsh in Georgia over a year. He also measured the aboveground biomass of the dominant primary producers, which were grasses, as well as the biomass of the dominant consumers, including insects, spiders, and crabs. Teal also measured the detritus that flowed out of the marsh to the surrounding coastal waters. To determine the amount of energy in each unit of biomass, he dried the biomass, burned it in a calorimeter, and measured the amount of heat produced. Form of Energy kcal/(m^2⋅yr)
Solar radiation 600,000
Gross grass production 34,580
Net grass production 6,585
Gross insect production 305
Net insect production 81
Detritus leaving marsh 3,671

Required:
a. Graph the data depicted above.
b. What proportion of the solar energy that reaches the marsh is incorporated into gross primaryproduction? Into net primary production? (A proportion is the same as a percentage divided by 100.Other measures are useful for comparing relative efficiencies across different ecosystems.)

i. Gross Primary- 0.058
ii. Net Primary-0.012

c. Trophic efficiency is the percentage of production transferred from one trophic level to the next. What isthe trophic efficiency between the producers and consumers?If the efficiency is not 100% how muchenergy is lost?
