Answer :
Answer: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.
Explanation:
The energy that is passed through to the primary consumer is only 10% of their total energy as 90% of energy is lost in the metabolic process or excretions process.
The flow of energy in any ecosystem is linear from the sun to the consumers in an ecosystem. Energy is transferred from each trophic level to the next, however, only 10% of the energy of each level is transferred other 90% of energy is lost in the various process:
- transferred to the next trophic level: If energy passed through the primary consumer then 10% of the total energy will transfer to the secondary consumer
- Lost as heat or metabolic process: Most of the part of the energy is lost in performing various cellular functions and metabolic functions such as cellular respiration, digestion, reproduction, and others.
- Lost in excretion: some part of the energy is also lost in the excretion process.
Thus, the correct answer and possibilities are given above.
