Energy is with each increase in trophic level.

About 10 % of energy changes as its transferred to next level

Explanation:

The amount of energy decrease as it moves through the trophic levels as it moves from one trophic level to the other, large parts of energy are lost as it is transferred through the metabolic process. An example of a grassland ecosystem that has 10,000 Kcal of energy concentrate on the vegetation that will be transferred to the primary consumer in the food chain through the 10 % ratio and which further adds on the transfer in the food web. The number of support is dependent on size and the availability of energy richness at a tropical level.
