At the base of each food chain, there are producers, namely autotrophic organisms, ie capable of organizing the chemical compounds in the soil (or water), so as to independently produce food reserves (sugars, starch). This process can be achieved by using the energy provided by photosynthesis. The producers are the only living things that can convert solar energy (light energy + thermal energy) into chemical energy (binding energy).
In a food chain, there are more producers than consumers because producers are the only organisms that convert solar energy into chemical energy through photosynthesis. As energy is lost at each trophic level, a greater number of producers are required to support the consumers. This ensures a stable ecosystem where energy availability and resource needs are met.
