25% is the approximate production efficiency of this animal
Explanation:
Given ,
A ladybug eats 200 J of plant material
100 J is eliminated as feces
75 J are used in cellular respiration,
Now,
The approximate production efficiency of this animal :
200 - (100 +75) = 25 %
The most common organisms with exoskeletons are arthropods which include insects (bees, ants), arachnids (spiders) and crustaceans (lobsters and crabs).
