The trophic level is location of an organism in e food web
1. The number of people that can be fed by the grasshoppers is approximately <u>19 people</u>
2. The number of people that can be fed by the soybean crop is approximately <u>166 people</u>
3. Please find attached diagram of Biomass Pyramid
The reasons the responses are correct are as follows:
1. Required:
The number of people the grasshopper could feed
Solution:
The number of grasshoppers (gh) one chicken feeds on in a year is given as follows;
One chicken feeds on = 40 gh/day × 365 day = 14,600 gh
The number of people the gh will feed = 14,600 gh/(750 gh/day/person) ≈ <u>19 people</u>
2. Required:
The number of people the soybean can feed
Solution:
The number of grasshopper eating by the half chicken the farmer eats each day = 7,300 gh
Mass of soybean consumed by the gh = 7,300 gh × 25 g/gh = 182,500 g
The soybean calorie used = 182,500 g × 3.2 cal/g = 584,000 cal
The calorie consumed per day = 3,500 cal/day
The number of people = 584,000 cal/(3,500 cal/person) ≈ 166
The number of people the soybean crop feeds ≈ <u>166 people</u>
3. Required:
The diagram of the Biomass Pyramid
Solution:
The mass of the farmer = 75 kg
The mass of the chicken = 1.5 kg
The mass of chicken eaten = (1.5 kg/2) × 365 = <u>273.5 kg</u>
The mass of the grasshopper = 7,300 gh × 365/(1,200 gh/kg) ≈ <u>2,220.4 kg</u>
The mass of soybean = 7,300 gh × 25 g/gh × 365 = 66,612,500 g = <u>66,612.5 kg.</u>
