 Question 2: Evaluate the statements below and choose those that correctly apply to the factors governing nutrient supply in archaea.

• Often called “extremophiles”, archaea may inhabit a nutrient-poor niche necessitating an accumulation mechanism.Both ABC and symport/antiport mechanisms of transport are used by archaea to transport nutrients into the cell.The need to store nutrients that are in short supply requires the use of active transport to move molecules against their concentration gradient……….
