Input:  Person1:     I watched a very interesting documentary about plants yesterday evening . It was called unusual plants and looked at several species of plants from around the world which have unusual features .  
 Person2:  Really ? Tell me about some of the plants they showed .  
 Person1:      Well . There was one type of plant that catches insects and eats them .  
 Person2:  Is that type of plant found in this country ?  
 Person1:      No , it isn ’ t . it ’ s a pity , because I ’ d like to see it in action .  
 Person2:  So would i . what other unusual plants did they show ?  
 Person1:      They showed flowers that only provide their nectar to one type of butterfly or bee . The insect has to be the exact size to get the nectar . Other insects cannot get it . Of course , when the insect molle  
 Person2:  That ’ s very specialized . So , the insects and the flowers rely on each other . If one became extinct , the other would too .  
 Person1:      That ’ s right . That ’ s one reason why it ’ s so important to protect every species .  
 Person2:  I see . The plants that fascinate me most are cacti . I find it amazing that they can survive in such dry desert conditions .  
 Person1:      According to the documentary , they have an incredible ability to find water supplies , however small , and then store them without losing much through evaporation .  
 Person2:  That ’ s why they often have long roots to find water spines instead of leaves , to reduce water loss .
