10% of the energy in a system is lost to the environment

10% of all organisms are able to reproduce in each ecosystem

70% of energy in the previous trophic level is available to the next trophic level.

10% of all organisms in each trophic level will survive

The 10% rule refers to the idea that only about 10% of the energy from one trophic level is transferred to the next trophic level in an ecosystem. This means that as energy flows through the food chain, only a small fraction of the energy is passed on to the next level. This is often represented in energy pyramids, such as the one shown in the image.
