In, say, a food web??
Depends. There is always a portion of the potential energy which is lost as heat to the surrounding area, through excretion etc. So really it depends on the amount of energy received and then lost...impossible to tell without these values unfortunately.
Typically, about 10% of the energy is transferred from one trophic level to the next in a food chain or web. This is due to energy loss through metabolism and heat. This limits the number of trophic levels that can be supported in an ecosystem.

Because of the second law of thermodynamics, which states that each time energy is converted from one form to another, some of the energy is always degraded to a lower quality, more dispersed, less useful form and that no system can convert energy from one form to another useful form with 100% efficiency.
as little as 10% of the energy at any trophic level is transfer to the next level
Roughly 10% of energy is passed from one trophic level to the next, with the remaining 90% lost as heat through metabolic processes. This process is known as the 10% rule in energy transfer in ecosystems.

The exact details will surely vary from one organism to another, but in general, most of the energy is eventually converted to heat. A small amount may be stored as an energy reserve, for example as sugar, or as fatty tissue.
