Why is energy lost from an ecosystem at every transfer from one trophic level to the trophic level above it?

Summary Introduction

To review:

The loss of energy from an ecosystem at every transfer from one trophic level to another trophic level above it.

Introduction:

Energy is needed by every organism in an ecosystem for sustaining life. The net primary productivity supports the organisms present at each trophic level. The producers of an ecosystem convert solar energy into chemical energy, which flows through each trophic level, supporting all the consumers. However, not all the energy that is produced flows through each of the trophic levels. There is an energy loss at each trophic level while moving to another trophic level.

Explanation

The loss of energy during transfer from a trophic level to a higher trophic level may be caused by two factors. First, animals use energy, which they assimilate for various processes like locomotion and maintenance. Most of the energy is used up and the remaining is available for transfer. This results in loss of energy when transferring to another trophic level...
