Yes all living organisms need sun to survive
This is false for a number of reasons. While LH (which stands for Leutinizing Hormone) is released by the anterior pituitary gland and can be present in both females and males, it play a more predominant role in females. Working closely with FSH (Follicle Stimulating Hormone) a surge in LH begins the process of ovulation and the development of the Corpeus Leuteum.
In Males it is used both for the production of sperm but to stimulate the production of testosterone.

The answer is; seeds that store energy in sugar
Sugar is the main source of energy for most life. Oils and fats are used to store excess starch energy for later. Therefore seeds that store oil has to re-convert the oils to carbohydrates so as to respire, However, those that store sugars would just retrieve them from storage and directly use them in respiration.
The answer is; YES
Temperature is an important factor in germination and respiration rate. Optimal temperature range will enable the enzymes to be active and hydrolyze stored energy sources (such as oils and carbohydrates) for energy. Higher than optimal temperatures may denature the enzyme while low temperatures will deactivate the enzymes.
