Question

A population of insects consumes plants containing 350 j of energy and excretes 180 j in its feces. if 150 j of energy are used for respiration, what is the production efficiency for these insects?

Answer 1

Answer: 5.7%

Given:

350 j (total energy)

180 j (excretion in feces)

150 j ( energy for respiration)

Solution:

Let X= energy left in the body

X=350-180-150

X=20 j

Production efficiency is:

20/350=5.7%
