Top-Down Effects of Introducing Piscivorous Fish: Long-Term Impacts on Lake Food Webs
A small lake has three trophic levels- phytoplankton(autotrophs),Zooplankton (herbivore) and planktivorous fish (primary carnivore). Into this lake, a population of piscivorous fish (secondary carnivore) was introduced to study the ‘top-down’ effects”. What is the expected […]
