B. 100J
C. 10J
D. 1J

Answer 1

Hint: Transfer of energy in a natural pecking order adheres to the 10% law. It is liable for the decrease of energy at each trophic level. Henceforth in this manner there is a stream of energy that happens in the natural pecking order.

Complete answer:
Natural pecking order is the straight organization wherein there is transfer of energy and matter happens at each trophic level. The least level in the natural way of life is known as essential makers. This level involves all herbivores or plant eating creatures. At this level, the energy is viewed as 100%. As per the 10% law given by Lindeman, it is viewed as that during the exchange of energy starting with one trophic level then onto the next trophic level, just 10% of energy gets moved while the rest 90% is lost as warmth to the environmental elements. So in the event that 10000 joules of energy is accessible to the maker, 10% of 10000 will be moved to the essential buyer for example 1000 joules. Again to the optional shopper 10% of 1000 will be moved for example 100 joules. The energy accessible to the optional buyer is 100 joules to move to the tertiary shopper. The energy to the tertiary shopper is 10 joules.
The 10% law gives us the essential thought regarding the proficiency of the natural pecking order and furthermore about the cycles in the evolved way of life. This law is otherwise called Lindeman's trophic effectiveness law. The natural pecking order contains Primary producer (grass), Primary consumer (deer), Secondary consumer (lion).

So, by the law, the lion has 100J energy. Option B is correct

Note:
At the point when the natural way of life gets interlinked then it frames a food web which contains 2-3 evolved ways of life. Evolved way of life is essential for biological equilibrium and furthermore for the progression of energy and supplements. In the food web, the supplement's development is cyclic in nature while the energy stream is unidirectional and non-cyclic in nature.
