About how much energy is transferred from a primary consumer to a secondary consumer?
90% of the original energy from the sun
10% of the original energy from the sun
10% of the primary consumer's energy
1% of the primary consumer's energy

The correct answer is 10% of the primary consumer's energy.

According to the law of 10 % energy transfer-

10 % of the energy is transferred from one trophic level to the subsequent trophic level in a food chain. The remaining energy is utilized in the metabolic processes of the organism or released as heat in the atmosphere.

Primary consumer ( like herbivore) and secondary consumer ( like carnivore) are the trophic levels of the food chain. Primary consumers get energy by consuming producers like plants whereas secondary consumers obtain energy by eating primary consumers.

Thus, 10 % of the energy from the primary consumer is transferred to the secondary consumer.
