None. There is only a transfer of energy. You obtain the energy from a consumed source example: you eat food which causes a transfer of energy but the food does not provide energy.
A basic source of energy is food! we all need it for energy plants and animals alike need food we live in a dog-eat-dog world! because of the food web it is simple to get and eat!
well it would matter what the hawk had ate if a hawk ate a snake he would gain energy from eating the snake but also other things that the pray ate so i wold say its grass.
food
The sun light is the most important because while it cannot be used by humans directly, it can be used by plants to grow and provide food.
Chlorophyll is the source of all food energy on the planet earth.

The sun is the ultimate source of all energy in Earth's ecosystems.

The sun.Without the sun life on earth would soon stop because all available carbon (the basis of all life forms on Earth) would be used up.A few ecosystems get their energy partially or entirely from geothermal sources. The original source of this energy is radioactive decay heat from isotopes in the crust, mantle, and core.Both the sun and earth were formed from matter ejected and/or compressed by supernova explosions. So the original source for both the energy from the sun and from radioactive decay heat was supernovas.Ultimately the original source of all energy was the Big Bang.
the sun is the beginning of all food chains
