The producers or autotrophs are considered to store the most energy because

• as autotrophs they absorb energy from the sun and store it as glucose. they use most of this energy but give some off as heat. only 10% of their energy is passed on to the next level.

• they don't move so they don't burn as much energy.

• not many organisms eat autotrophs so the energy they store is safe with them.

• most plants are inedible and the energy they store does not ge passed to other organisms.
