Select the correct set of statement's :

I. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion

II. Irreversible work is always greater than reversible work.

III. On an ideal gas in case of single stage expansion and compression system as well as surrounding are restored back to their original states

IV. If gas is in thermodynamic equilibrium is taken from state A to state B, by four successive single stage expansions.

Then we can plot 4 points on the P—V indicator diagram.

(A) Consumption efficiencies for carnivores are typically higher than those of herbivores

(B) Assimilation efficiencies of herbivore are often less than consumption efficiencies

(C) Vertebrates tend to have lower production efficiencies than invertebrates

#XL - R Botany

Consumption efficiency (CE) is the proportion of production at one trophic level (Prodn n-1) that is eaten by, or ingested, by the next trophic level (In) but Assimilation efficiency (AE) is the proportion of ingested energy assimilated in to blood stream

Which of the following is incorrect statement?

A) In terrestrial herbivore, AE is greater than CE

B) In aquatic herbivore AE is equal to CE 

C) CE of grass land herbivore is often greater than forest herbivore

D) AE of herbivore is often greater than carnivore
