According to the law of conservation of energy, energy can neither be created nor destroyed. If this is true, why is there less energy
in the top of the energy pyramid than there is in the bottom of the energy pyramid?
OA. The extra energy in the bottom is slower to reach the top.
OB. Energy is lost between each trophic level as heat.
OC. The law of conservation of energy does not apply to ecosystems.
OD. Organisms in the top of the energy pyramid use up energy the fastest.



Answer :

Final answer:

Energy is lost as heat between trophic levels, leading to less energy at the top of the pyramid, impacting the number of organisms at higher trophic levels.


Explanation:

Energy is lost between each trophic level as heat due to the inefficiency of energy transfer in ecosystems, with only about 10% passing on to the next level.

This energy loss results in less energy available at the top of the pyramid compared to the bottom, leading to fewer organisms at higher trophic levels.

In ecosystems, the law of conservation of energy applies but the complex interactions and energy transformations lead to a decrease in available energy at each trophic level.
