What is true of energy as is passes through an ecosystem?
All of the energy in an organism is used by the animal that eats it.
Any stored energy in an organism is used by the animal that eats it.
About 50 percent of the energy in an organism is used by the animal that eats it.
About 10 percent of the energy in an organism is used by the animal that eats it. **
Correct, About ten percent of the energy in an organism is used by the animal that eats it is passes through an ecosystem.
Thank you!
You are welcome!
The correct answer is: About 10 percent of the energy in an organism is used by the animal that eats it.
This concept is related to the ecological pyramid, specifically the energy pyramid. In an ecosystem, energy flows through different trophic levels, which represent the different levels of the food chain.
At each trophic level, there is a transfer of energy as organisms consume other organisms to obtain their energy. However, only a fraction of the energy is actually passed on to the next trophic level. This is due to various inefficiencies in energy transfer, such as heat loss during metabolism, incomplete digestion, and energy used for movement and other metabolic processes.
Typically, the transfer of energy from one trophic level to the next is about 10 percent efficient. This means that for every unit of energy consumed by an organism, only about 10 percent of that energy is converted into biomass and is available as food for the next trophic level. The rest of the energy is lost as heat or used for other purposes by the consuming organism.
Therefore, out of the total energy in an organism, only a small portion (about 10 percent) is available for consumption by the animal that eats it, while the rest is either not consumed or lost as waste in the form of heat or in other metabolic processes.
