Answer 2

The three characteristics of flow of energy in ecosystem is given below :

1. Energy flows only in one direction

The energy always flows in one direction or path only. For example : The energy that passes from the autotrophs to the herbivores never reverts back from herbivores to the autotrophs.

2. Decrease in energy progressively :

The energy always decreases at subsequent tropic levels. It is because everytime when energy is tranferred from one tropic level to the other, some amount of energy gets lost.

3. Cycling of energy

The energy gets circulated like the nutrients.
