The invasion of a tiny insect name ‘Eretmoptera murphyi’ is changing the ecosystem of which continent?

  • A. Saudia Arabia
  • B. Antarctica
  • C. Canada
  • D. Africa

Correct Answer: B. Antarctica

Eretmoptera murphyi is a flightless midge. It is currently changing Antarctica’s Signy Island soil and ecosystem by feasting on dead organic matter. It has led to fast plant decomposition, thus increasing the soil nitrate level by three-five times compared to places on the island where the midge is absent.
