Unicellular organisms are able to move towards and away from heat just like animals can. So if the temperature is too severe then the organism can move away. However most unicellular organisms like to live in severe temperatures.
Unicellular organisms meet their basic needs by metabolism (eating, drinking, breathe, and excrete) , growth (how big do they grow), Reproduction, irritability (how do they react to heat and cold, how do they react to danger), adaptation (how do they compete for food and space to survive) and movement (how do they move).
