Answer 1

commonly是副词修饰整个句子，主句是fields are natural home to frogs.非限制性定语从句where they enjoy a comfortable life feeding on pest harmful to crops修饰fields.动名词分句helping solve the big headache of farmers做定语修饰前面的从句。

Answer 2

Commonly 作为插入语
fields are natural home to frogs 这是主语
where they enjoy a comfortable life feeding on pest harmful to crops 这句作为主句的地方作为非限制性定语从句
helping solve the big headache of farmers这句作为主句的伴随状态
