Question

10% law explain with an example

Answer 1

When energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.

Answer 2

$%$Answer: According to $10%$% law, in every successive stage of food chain, only $10$% of energy is transferred to the next trophic level.

For example, the food chain is as follows-

Plants → Grasshopper ​​​​​​​→ Frog ​​​​​​​→ Snake ​​​​​​​→ Bird

If the producer (Plant) has 100,000J, the next trophic level will be passed on only 10% of energy, which is 10,000J. The similar process will continue till the end of food cycle.

Plants →    Grasshopper ​​​​​​​→   Frog ​​​​​​​→    Snake ​​​​​​​→   Bird

100,000J     10,000J          1000J            100J         10J

Thus, only 10J energy is available to the Bird.
