Which of the following ecosystems would likely have the largest net primary productivity per hectare and why?

#Part-B Specialized Branches in Biotechnology
  1. open ocean, because of the total biomass of photosynthetic autotrophs
  2. grassland, because of rapid growth, the small standing crop biomass that results from consumption by herbivores, and rapid decomposition
  3. tundra, because of the incredibly rapid period of growth during the summer season
  4. deep ocean, due to the high activity of chemoautotrophs at deep sea vents

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

#Part-B Specialized Branches in Biotechnology

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?
