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?

#Part-B Specialized Branches in Biotechnology
  1. Zooplankton biomass will increase and phytoplankton biomass will decrease.

  2. Zooplankton biomass will decrease and phytoplankton biomass will increase.

  3. The biomasses of zooplankton and phytoplankton will increase while planktivorous remain unchange

  4. The biomasses of all tropic level increases
