In an ecosystem, the transfer of energy from one trophic level to the next is known as "energy transfer efficiency." The amount of energy that is typically transferred from one trophic level to the next is around 10%. This means that only about 10% of the energy available at one trophic level is passed on to the next level.
The remaining 90% of the energy is not transferred and is lost in various ways. The major portion of this energy is lost as heat through metabolic processes, such as respiration and other physiological functions. Some energy is also lost as waste products, such as feces or urine.
The low energy transfer efficiency between trophic levels is primarily due to the laws of thermodynamics. It is more efficient for organisms to convert energy from one form to another (such as converting solar energy into chemical energy through photosynthesis) rather than transferring it directly. This inefficiency limits the length and complexity of food chains or ecological pyramids within an ecosystem.
It is important to note that due to the low energy transfer efficiency, ecosystems require a large base of primary producers (plants or algae) to sustain higher trophic levels (herbivores, carnivores, etc.). This is because the energy available at each trophic level diminishes significantly, resulting in the need for a broader base to support the energy requirements of the higher levels.
energy transfers through an ecosystem. How much energy is typically transferred from one tophic level to the next? What happens to the other 90%?
