If the 2° consumers have 467 kcal, how much energy did the producers have?
Thank you to any 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.

The three types of plate boundaries are ;
The divergent plate boundary ; This boundary is formed when tectonic plates move away from each other thereby forming new crust below the earth in the process
Convergent plate boundary ; This plate boundary is formed by the collision of two or more tectonic plates. If one of colliding plates is an Oceanic crust tectonic plate the collision will lead to a subduction
Transform plate boundary ; At this boundary tectonic plates slide pass one another without having any significant effect on the earth crust
Hence we can conclude that the three types of plate boundaries are ; Divergent , convergent and transform
