Apopulation 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?

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%

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
