Typically, only about 10% of the energy from one trophic level is transferred to the next level in an ecosystem. This phenomenon is known as the 10% rule and occurs due to energy loss through metabolic processes, heat, and waste. As a result, higher trophic levels have less available energy, which limits the number of organisms that can be supported at these levels.

In an energy pyramid, only about 10% of the energy from one trophic level is available to the next level. Therefore, if 1000 kcal is available at the first trophic level, approximately 100 kcal would be available at the second trophic level. At the third trophic level, only about 10% of that energy would be available, resulting in roughly 10 kcal.
If the first trophic level has 300,000 kilocalories and there is a 90 percent loss of energy between trophic levels, then only 10 percent of the energy is passed on to the next level. Therefore, the second trophic level would have 30,000 kilocalories (10% of 300,000). Applying the same loss rate, the third trophic level would have 3,000 kilocalories (10% of 30,000).
as little as 10% of the energy at any trophic level is transfer to the next level
Typically, around 10% of the energy is transferred from one trophic level to the next, with the rest being lost as heat. The energy not transferred is usually used for metabolic processes, growth, and reproduction by the organisms in each trophic level.

An energy pyramid is used to show how much energy is used in each trophic level in an ecosystem. This pyramid represents the flow of energy from one trophic level to the next, with energy decreasing as it moves up the pyramid.
as little as 10% of the energy at any trophic level is transfer to the next level
Approximately 10% of the energy is passed from one trophic level to the next in an energy pyramid. This means that as you move up the trophic levels, less energy is available for the organisms at higher levels.
Roughly 10% of the energy from one trophic level is transferred to the next trophic level. This loss of energy occurs mainly through metabolic processes such as respiration and heat loss, resulting in less energy being available for the next trophic level.
The trophic level of an animal refers to its position in a food chain or food web based on its diet and energy source. Animals higher up in the trophic levels depend on consuming other organisms lower in the food chain for energy.
Typically, around 10% of the energy is transferred from one trophic level to the next, with the rest being lost as heat. The energy not transferred is usually used for metabolic processes, growth, and reproduction by the organisms in each trophic level.
Only 10% moves up...my daughter is writing a paper on this now!
Each trophic level has about 10% less energy available than the level below it. This is due to energy being lost as heat during metabolic processes and as it moves up the food chain.
