Antarctica is not just a land of ice and snow – it is the coldest, driest climate on earth. When we say the word ‘desert’, we might imagine sand and camels, but in fact a desert is any place that receives less than 25 centimetres of rain in a year, making Antarctica a large cold desert. Not all of Antarctica is covered in snow – some of the inner regions of Antarctica (called the Dry Valleys) have large areas of uncovered rock.
The connection between organisms within ecosystems can be described based on whether they are producers or consumers of energy.
Who are the producers?
Antarctica has no trees or shrubs but it is far from being lifeless. Plants living in Antarctica must overcome two major factors: the cold temperatures and the lack of rainfall – they must have a regular water supply or the ability to go dormant for periods of time.
