d. The percentage of the original energy from producers that's available to the consumer is quite small.

The 10% energy rule.

This energy rule states that every energy that is transferred from one organism to the other decreases by 10%. For example, a plant has created food thru photosynthesis gained 1000J and a cow eats it it would receive an energy of 100J and a human eats the cow would receive 10J.
