Approximately what % of the energy taken in by a consumer is used to create new body tissue? 10-40% 0-5% 40-60% 70-90%

The correct option is 0 -5%.
The conversion of assimilated energy into new tissue is called secondary production. The percentage of assimilated energy that is converted to new tissue varies among living organisms. In vertebrates, the percentage is about 2%. This percentage is as low as this, because vertebrates need high amount of energy to maintain constancy in their internal environment, so most of the energy is used for this.
