The new population that experienced natural selection is now better fit or more adapted to the environment than the old population
The correct answer is option Energy is lost at each trophic level.
In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.
The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.
