Explanation:

The term of office of the AG is not fixed by the Constitution. Further, the Constitution does not contain the procedure and grounds for his removal. He holds office during the pleasure of thepresident. This means that he may be removed by the president at any time. 
The chairman or a member of the UPSC can be removed from office by the president only in the manner and on the grounds mentioned in the Constitution. Therefore, they enjoy security of tenure. The President can remove the chairman or any other member of UPSC from the office under the following circumstances:
(a) If he is adjudged an insolvent (that is, has gone bankrupt);
(b) If he engages, during his term of office, in any paid employment outside the duties of his office; or
(c) If he is, in the opinion of the president, unfit to continue in office by reason of infirmity of mind or body.
In addition to these, the president can also remove the chairman or any other member of UPSC for misbehaviour. However, in this case, the president has to refer the matter to the Supreme Court for an enquiry. If the Supreme Court, after the enquiry, upholds the cause of removal and advises so, the president can remove the chairman or a member. Under the provisions of the Constitution,
the advice tendered by the Supreme Court in this regard is binding on the president. During the course of enquiry by the Supreme Court, the president can suspend the chairman or the member of UPSC.
A governor holds office for a term of five years from the date on which he enters upon his office. However, this term of five years is subject to the pleasure of the President. Further, he can resign at any time by addressing a resignation letter to the President.
