Question

A Viceroy caterpillar feeds on a leaf. One day's feeding consumes 1000 calories worth of leaves. 50% of the calories are lost in its feces and 33% of the calories are used in cellular respiration.How many calories of the original intake are available to add to the caterpillar’s biomass each day?
A. 830 caloriesB. 330 caloriesC. 500 caloriesD. 170 caloriesE. 670 calories

Answer 1

Answer: 170 calories.

Explanation:

The Viceroy caterpillars feeds on the green plants and trees for its survival. The total energy that is incorporated in the body of the caterpillar is used in cellular respiration, faces and rest amount of the energy left is used as biomass by the caterpillar each day.

The total energy is 1000 calories, 50% of this energy is 500 calories which is released out of the body through faces. Rest 33% of total energy( 330 calories) is used in cellular respiration.

The rest amount of energy that is available is 170 calories.
