    In this interaction, the interacting species stay close together

  • Predation, Parasitism, Commensalism
  • Competition and Mutualism
  • Amensalism, Commensalism
  • Amensalism, Predation and Parasitism
  • 2. 
    Predation can be considered as

  • predator’s way of controlling prey’s energy level
  • nature’s way of controlling predators food chain
  • nature’s way of transferring energy to higher trophic levels
  • prey’s way to control the population
  • 3. 
    This cannot be performed by predators

  • allowing herbivores to be filled with energy fixed by autotrophs
  • make the ecosystem stable
  • controls the species of prey
  • conduit for the transfer of energy
  • 4. 
    Prey is small, predator is massive, typically filter feeders – whales and zooplankton and lichen, graph is found to be linear

  • Functional response
  • Type 3 functional response
  • Type 1 functional response
  • Type 2 functional response
  • 5. 
    This can be a predator in a broad ecological context

  • crow
  • tiger
  • lion
  • seed eating sparrow
  • 6. 
    Predators which consume almost everything are

  • generalist predators
  • predation
  • predators
  • specialist predators
  • 7. 
    The reason why exotic species starts dispersing fast and turns invasive is

  • because of successful establishment of the food web
  • because of the lack of natural predator
  • because of lack of competition from other exotic plants
  • it gets better nutrition there
  • 8. 
    In an ecosystem, if you discard predators in a hypothetical scenario causing few species to become extinct, it indicates

  • commensalism
  • parasitism
  • interspecific competition
  • intraspecific competition
  • 9. 
    The starfish Pisaster amongst the rocky intertidal communities of the American Pacific coast is a significant

  • Competitor
  • Parasite
  • Predator
  • Prey
  • 10. 
    Predators suppression of prey declines with the increasing impact of prey on the next lower trophic level such as the impact of herbivores on plants – this is

  • Predation cycles
  • Parasitism
  • Trophic cascades
  • Top down
