Energy can be lost in a food chain by heat or waste.
ATP is an immediate source of energy for animals and all living things.
In a food chain or energy pyramid, approximately 10% of the energy from one trophic level is transferred to the next level. This is known as the 10% rule, which reflects the energy lost through metabolic processes, heat, and waste at each level. As a result, energy diminishes significantly as it moves up the food chain, leading to fewer organisms that can be supported at higher trophic levels.
Heterotrophs get energy by eating plants. The process is called food chain.
As a general rule, ecosystems with the largest populations tend to be those at the base of the food chain, such as producers like plants and phytoplankton. These organisms capture sunlight and convert it into energy through photosynthesis, providing a vital energy source for herbivores and, subsequently, carnivores. The availability of energy decreases at each trophic level, resulting in fewer individuals as you move up the food chain. Consequently, ecosystems with abundant primary producers typically support larger populations overall.
plants
The sun is the major source of energy for the food chain through a process called photosynthesis. Plants, algae, and some bacteria capture sunlight to convert it into chemical energy that is then passed on to consumers in the food chain.
Producers
It starts with a primary energy source.

Because when you eat you get energy and a food chain tells you which animal eats what

The transfer of food energy from one organism to another in stages is called a food chain. In a food chain, energy is passed from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores) and so on. Each transfer of energy represents a trophic level in the ecosystem.
Plants are always the base of any food chain.
,ultimately, it comes from the sun.
