Question

Q.6. “It is often said that the pyramid of energy is always upright. On the other

hand, the pyramid of biomass can be both upright and inverted.” Explain with the

help of examples and sketches.​

Answer 1

Answer:

ok

Explanation:

The diagrams show ecological pyramid, it is graphically represented to show the biomass or productivity of the biomass at each trophic level in an ecosystem.

According to ten percent law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the energy is transferred from one trophic level to another. The remaining is lost during transfer, broken down in respiration, or lost to incomplete digestion by higher trophic levels. In the example given, as 10000J of energy is produced by producers, but only 1,000J is transferred to primary consumers and same way only 100J is transferred to secondary consumers
