egested waste/day 648 kcal
food ingested/day 2592 kcal
what percentage of ingested food is used for maintaining biomass in organism b? * 1 point
o 25.8%
o 16.1%
o 58.1%
o 9.7%
which statement best explains \egested waste\? * 1 point
o energy lost as heat
o food converted to biomass
o material excreted from the body
o energy stored as fat

Explanation:

1. First question solution

Step1: Calculate energy used for maintaining biomass

For the lion (Organism B), energy used for maintaining biomass = Food ingested - (Respiration + Heat loss+ Egested waste). Food ingested = 2592 Kcal, Respiration = 829 Kcal, Heat loss = 726 Kcal, Egested waste = 648 Kcal. So energy used for maintaining biomass = 2592-(829 + 726+648)=389 Kcal.

Step2: Calculate the percentage

Percentage = $\frac{\text{Energy for biomass}}{\text{Food ingested}}\times100=\frac{389}{2592}\times 100\approx15.0\%$. The closest answer to this value among the options is 16.1%.

Egested waste refers to the undigested material that is excreted from the body. It is not related to heat - loss, conversion to biomass or energy stored as fat.

Answer:

16.1%
