Asparrow eats 1200 j of seeds. of this, 425 j is eliminated as feces and 750 j are used in cellular respiration. what is the approximate production efficiency of this animal?

0.625 (62.5 %)

Explanation:

The production efficiency is equal to the rate between the energy converted into useful energy and the energy in input:

where in this case:

- the useful energy is 750 J (the energy used in cellular respiration)

- the energy in input is 1200 J (the energy taken by eating the seeds)

Substituting,

Which means an approximate efficiency of 62.5 %.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

thermal energy is the answer
