Query to find dependency of an oracle VIEW

Question

Hi,
I'm using oracle 10g database.
DB name is - ORCL
ORCL DB consists two schemas - Schema1 and Schema2
I have one Oracle view called VIEW1 in Schema1.
I need to find whether Schema2 uses VIEW1 in any of the Tables,views or Programs owned by Schema2.
Is there any query available to find this one?
Regards,
Karthik

How about querying the dba_dependencies view?
SQL> conn / as sysdba
Connected.
SQL> conn aman/aman
Connected.
SQL> create table t as select * from scott.dept;
Table created.
SQL> create view v1 as select * from t;
View created.
SQL> grant select on v1 to scott;
Grant succeeded.
SQL> conn scott/tiger
Connected.
SQL> create view v_dependant as select * from aman.v1;
View created.
SQL> conn / as sysdba
Connected.
SQL> desc dba_dependencies
