The amount of usable energy ("food") stored in the biomass of organisms is decreased because most of the energy taken in by consumers is used for movement or released as body heat. The percentage passed on is usually taken as 10%, although this is a very generalized average, and different ecosystems have varying efficiencies.
Most of this energy gets used up - converted into unusable energy.
What happens is that throughout the food chain the energy stays the same.
Energy is lost
sun light
the energy amount increases as other organisms eat other organizms.
the amount of energy decreases the further up the food chain you go
who gets the least amount of energy in the food chain
Energy is released.
Every step of energy transformation have loss. Progress through the energy chain, the amount of energy transferred would unavoidably degraded. So as the chain progress it get narrower to a pyramid shape.
The energy in a food chain transfers through the organisms involved in it.
It decreases because there are less and less animals as you go up.
Energy is transferred through a food chain when an organism eats another organism. As the food chain progresses, less energy is available when an organism is consumed.
The energy flux of a food chain goes from producer to decomposer. The energy flux along the food chain is always unilateral.
