the main source of energy of all food chain is the sun.Basically it provides the energy for green plants to overcome the process of photosynthesis, the making of food.
The sun its so simple
The sun is the ultimate source of all energy in Earth's ecosystems.
Simplistically, the Sun (sunlight) is this ultimate energy source. BUT.... There are some ecosystems (those round black smokers in the deep oceans - or bacteria that live deep down in the solid rock of the earth) which use chemical energy produced by the heat within our planet as their energy source. organic food and its oxidation during respiration.
The energy source at the bottom of most food chains is the Sun.
