The plants that manufacture food from the Sun are known as the primary producers while the consumers are the animals and other organisms that feed on other organisms
The correct responses are;
1. The number of people the grasshopper feeds is about 15 people
2. The number of people the soybean crop feeds is 23 people
3. Please find attached the diagram for the Biomass Pyramid
The reason the above responses are correct are as follows:
Question: The missing assumptions of the question can be taken as follows
The daily consumption the farmer can live on = 1 hen per day for a year
One hen eats 25 grasshoppers (gh) per day
The farmer requires 600 gh/day
The mass of 1,000 gh = 1 kg
The quantity of soy bean required by one gh for a year = 30 g/year
3.3 calories are contained in one gram of dry soy bean
1. The number of grasshoppers the chicken eats in a year = 25 × 365 = 9,125
The hen eats 9,125 gh to grow before being eaten
The number of people the gh feeds = 9,125 gh/(600 gh/person) ≈ 15 people
The grasshoppers feed 15 people
2. The amount of calories the farmer consumes per day = 3,500 calories
1 gh eats 30 g soy/yr
1 chicken eats 9,125 gh per year
The mass of soybean eating by the grasshopper = 9,125 × 30 g = 273,750 g
The calories in the soybean = 273,750 g/(3.3 cal/g) ≈ 82,954.5 cal
The number of people the soybean feeds = 82,954.5/3,500 ≈ 23
The number of people the soybean feeds ≈ 23 people
3. The mass of chicken the farmer needs in a year = 365 × 1.5 kg = 547.5 kg
The mass of the grasshoppers needed = 9,125×365/1000 = 3,330 ��kg
The mass of soybean needed = 9,125 × 30/1000 = 99,918.75 kg
