Question

A cow ingests 100 kilojoules of energy from eating grass of which 60 kilojoules are egested. An additional 30 kilojoules of energy are lost through respiration. The assimilation efficiency of the grass the cow ate: (Check all that apply.)

Can be calculated by subtracting the energy egested from the energy ingested

Can be calculated by dividing the assimilated energy by the ingested energy.

Can be calculated by dividing the assimilated energy by the egested energy.

Is 40%.

Is 10%.

Explanation / Answer

Answer:

Can be calculated by subtracting the energy egested from the energy ingested

Is 10%.

Explanation:

The assimilation efficiency (AE) = I?E

Where "I" is the ingestion rate and "E" is the egestion (defecation).

AE= 100-60-30=10%
