Answer 1

Biotic factors of an ecosystem are linked together for food and form a chain called food chain. The various steps in the food chain are called trophic levels. According to the pyramid of energy, the energy flows from one trophic level to the next in one direction only.
As the autotrophs (green plants) form the base of the food chain, they have the highest amount of energy.
