Question

the pyramid below shows the transfer of energy through a terrestrial (land) ecosystem.
according to this information, how much energy will be available to the third - order consumers?
a 0.1 kj
b 10 kj
c 1 kj
d 0.01 kj

Explanation:

Step1: Understand energy transfer rule

In a terrestrial ecosystem, about 10% of energy is transferred from one trophic level to the next.

Step2: Calculate energy for second - order consumers

If producers have 10000 kJ, first - order consumers (herbivores) get \(10000\times0.1 = 1000\) kJ.

Step3: Calculate energy for third - order consumers

Second - order consumers (carnivores that eat herbivores) get \(1000\times0.1=100\) kJ. Third - order consumers (carnivores that eat second - order consumers) get \(100\times0.1 = 10\) kJ.

Answer:

B. 10 kJ
