It is the primary producers
Sunlight is the initial source of energy for most ecosystems. The producers convert light energy into chemical energy through photosynthesis. Energy transformations are yet never fully efficient and energy will escape from the ecosystem.The chemical energy then passes through the trophic levels of the ecosystem, where herbivores obtain energy from eating plants and carnivores obtain their energy from eating other animals. As for decomposers, they obtain their energy from waste products. Energy cannot be fully transferred between the trophic levels and it is only around 10% efficient as some energy is lost as heat through respiration.
trophic level
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
In each trophic level, some energy does not go to the consumer, and instead is released to the environment in the form of kinetic energy or wasted chemical energy.
Trophic level
This is because energy is lost at each trophic level. The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.

Trophic level
About 10% of the energy in the lower trophic level is passed to the next higher level. The 80% of energy that is left is used by that lower level for life processes or is lost as waste.
When an organism from a higher trophic level eats one from a lower trophic level, it gains energy and nutrients from the consumed organism. This contributes to the transfer of energy through the food chain and helps regulate population sizes in the ecosystem.
trophic level
Some energy transferred at each successive trophic level enters the environment as heat.
The trophic level of an animal refers to its place on the energy pyramid. Its trophic level shows what the animal eats and how much energy it gets.
Energy that is lost at each trophic level of an ecosystem is replenished by the producers. The producers get it from the sun.
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
