Question

A consumer eats 1500 J of food energy. The consumer uses 15 percent of the food energy for new biomass and the rest for cellular respiration and waste. How many joules of food energy were converted into new biomass?

Answer 1

When a consumer eats 1500 J of food energy and uses 15% for new biomass, 225 joules are converted into new biomass.

Step-by-step explanation:

The student asked how many joules of food energy were converted into new biomass when a consumer eats 1500 J of food energy and uses 15 percent of that energy for biomass, with the remainder used for cellular respiration and waste.

To find the answer, we can simply calculate 15% of 1500 J.

0.15 × 1500 J = 225 J

Therefore, 225 joules of the food energy were used to create new biomass.
