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.

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.

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.

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

What form is energy in when it enters a food chain and what form is energy in when it leaves a food chain?

Energy enters a food chain in the form of sunlight, which is converted into chemical energy by producers through photosynthesis. When energy leaves a food chain, it is typically in the form of heat after being used by organisms for metabolism and daily functions.


In any food chain the total amount of energy always?

The energy flux of a food chain goes from producer to decomposer. The energy flux along the food chain is always unilateral.


What in a food chain adds energy to every part of the food chain?

Producers, such as plants, are the organisms in a food chain that add energy to every part of the chain. They do this through the process of photosynthesis, where they convert sunlight into energy that can be used by other organisms in the food chain.


Transfer of food energy from one source to another in stages is called 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.


In a food chain what organism eats the producer?

The organism that eats the producer in a food chain is known as a primary consumer or herbivore. These organisms feed directly on plants or algae for energy.
