During follicular phase, it helps in the ovulation while during luteal phase it plays an important function of preparing the endometrium lining of the uterus. In addition, it also inhibits or decreases the production of FSH and LH during this phase with the help of negative feedback mechanism.

Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change .
Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.
