Environmental factors such as photoperiod and temperature can alter the levels of active gibberellins by affecting gene transcription for specific steps in the biosynthetic pathway such as;
a) Promotion of germination by light has been shown to be
due to increases in GA1 levels resulting from a light-induced increase in the
transcription of the gene for GA3ox, which converts GA20 to GA1
b) level of GA20-oxidase occurs in the highest amount in
shoot tips and elongating stems, is increased under long-day conditions. The fact that GA 20-oxidase is the enzyme that
converts GA53 to GA20
c) Giving cold treatment
of Thlaspiarvense and a return to high temperatures, the ent-kaurenoic
acid is converted to GA9, the most active gibberellin for stimulating the
flowering response
d) Potato plants overexpressing the GA20ox gene showed
tuberization, whereas transformation with the antisense gene for GA20ox
inhibited tuberization
Which of the following from the given above statements is correct?

Autotrophs in the aquatic ecosystem, unlike their counterparts in the terrestrial ecosystem are mostly microscopic and very low in indigestible (to the herbivores) matter. Following some observation are given?
A) Tropic level transfer efficiency is greater in aquatic ecosystem than terrestrial ecosystem
B) Tropical forest herbivores have higher consumption efficiencies than grassland herbivores
C) Flow of energy and nutrient is rapidly in aquatic ecosystem than terrestrial
D) Production efficiency of higher tropic level is greater than lower tropic level
