Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects. The introduction of lizards may lead to .  

1. a) commensal-host

b) parasite-host

c) prey-predator

b) an increase in the number of frogs

c) no population change in any of the three species

1. c) prey-predator  

2. a) competition between lizards and frogs for food

2. Introduction of lizards in the same region will increase the competition between lizards and frogs as their food is same that is small insects. Both frogs and lizards have same source of food (small insects), so lizard and frogs will fight for the same food.

Hence, the correct answers are 1. c) prey-predator  

2. a) competition between lizards and frogs for food .
