A small lake has three trophic levels- phytoplankton (autotrophs), Zooplankton (herbivore) and planktivorous fish (primary carnivore). In this lake, addition of nutrients is allowed to study the 'bottom up' effects". What is the expected biomass of phytoplankton and zooplankton tropic levels?

Ecologist have proposed following explanation to lead maximize biodiversity at tropic.

A. Higher productivity in the tropics allows for more species present

 B. Old communities have greater species than younger community

 C. Natural enemies such as predators and parasite limit competition in the tropics, which allows more species to coexist

D. Very less intensity of disturbances in the tropics promote high succession diversity

Analysis of mRNA from tomato fruits from wild-type and transgenic tomato plants genetically engineered to lack ethylene has revealed that gene expression during ripening is regulated by at least two independent pathways;

I) Ethylene-dependent pathway

II) Ethylene-independent pathway

Some given genes involved in these two pathways,

a) ACC oxidase

b) respiratory metabolism

c) ACC synthase

d) chlorophyllase

e) lycopene and aroma biosynthesis

Which of the following is the correct combination from the given pathways and its included genes?
