Where does the energy come from in a food chain?

Answer 1

In a green plant

There are photosynthetic organisms beside plants(Cyanobacteria, etc.). The energy for photosynthesis comes from the Sun. There are also organisms that can get energy from chemicals. Such as chemicals released from hydrothermal vents. That energy may have ultimately came from other stars that exploded long ago(elements made in the core of those stars that is now generating heat in the Earth via nuclear decay). So for life as we know it all food starts with energy directly or indirectly from stars. That energy came from nuclear fusion of light elements. Those light elements came from the Big Bang.

Answer 2

The energy in a food chain comes from the sun. Plants, as producers, use sunlight to convert it into chemical energy through photosynthesis. This energy is then transferred through the food chain as organisms consume one another.

Answer 3

All life on Earth depends on the energy from our sun. The sun provides energy for plants and bacteria. Animals feed on those and on each other. So everything comes from the sun.

Answer 4

It all starts from the sun then to the producer (plant) then the herbivore (only eats plants) then carnivore (eats meat)

Answer 5

Plants or producers are the first link in the food chain and they get their energy from the sun.

Answer 6

Either the producer or the sun
