How does photosynthesis and cellular respiration move carbon, nitrogen, and water through the different Earth systems (biosphere, atmosphere, hydrosphere, and geosphere)?

well the plants live and die from life to death they get there nutrients from water from rain. and oxygen from the air and nitrogen from the ground. the plant grows and dies. when it dies it decompose and puts nitrogen back into the soil along with the seeds that where produced in it's life time.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
