PLEASE HELP ME! I really need to pass :DIf a producer has 23,400 kcal of energy, how much energy will the 3° consumers receive?
and
If the 2° consumers have 467 kcal, how much energy did the producers have?
Thank you to any answers!
Answers
a) 23.4 Kcal is the energy will the 3° consumers receive.
b) 46700 Kcal is the energy producers have.
Explanation:
The energy value is given for the trophic levels. There is a 10 % rule of energy transfer which is applicable to the producers and consumers in the energy pyramid. According to it 10 % energy is transmitted to upper level in a pyramid while 90% gets dissipated in the form of heat.
Energy of producer = 23400 kCal
energy transferred to tertiary consumer = ?
At first the energy transferred to primary consumer is calculated as:
10 % of 23400 Kcal
x 23400
energy transferred to primary consumer = 2340 Kcal
energy transferred to secondary consumer:
10% of primary consumer energy
x 2340
= 234 Kcal
energy transferred to tertiary consumer:
10% of energy of secondary consumer
x 234
= 23.4 Kcal
Tertiary consumer will recieve 234 Kcal of energy.
b) Energy of secondary consumer is 467 Kcal
energy of producers =?
energy of producer was 100 times the energy of secondary consumer
467 x 100
= 46700 Kcal.
