select all the correct answers.\nin grasslands, goats are prey for both foxes and tigers. if the population of goats decreases because of natural causes, what are three possible consequences?\n□ there will be interspecific competition between foxes and tigers.\n□ there will be intraspecific competition between foxes and tigers.\n□ the energy received at the trophic level of carnivores will be less than the usual amount.\n□ the energy received at the trophic level of carnivores will be more than the usual amount.\n□ there will be decreased biomass at the trophic level of carnivores.

Answer

Brief Explanations:

  • Inter - specific competition occurs between different species for the same resource. Since foxes and tigers both prey on goats, with fewer goats, they will compete with each other (inter - specific), so the first option is correct.
  • Intraspecific competition is within the same species, not between foxes and tigers, so the second option is incorrect.
  • Goats are prey for carnivores (foxes and tigers). Fewer goats mean less energy available for the carnivore trophic level, so the third option is correct and the fourth is incorrect.
  • With less energy available at the carnivore trophic level, there will be decreased biomass as there is not enough energy to support as large a biomass, so the fifth option is correct.

Answer:

  • There will be interspecific competition between foxes and tigers.
  • The energy received at the trophic level of carnivores will be less than the usual amount.
  • There will be decreased biomass at the trophic level of carnivores.
