Answer:
Hormone levels are changing during menstruation and ovulation. The general trend of hormones after ovulation -when an individual approaches menstruation- is that hormone levels generally decrease.
Explanation:
In a woman's menstrual cycle, hormone levels tend to increase or decrease according to reproductive requirements. On the days close to ovulation, the hormones must prepare for the release of an egg and the preparation of the female reproductive organs for the possibility of an embryo.
If fertilization of the egg does not occur, hormone levels generally tend to decrease until menstruation occurs.
In the attached graph (picture) the behaviour of hormones in an adult woman can be clearly seen, where estradiol, follicle-stimulating hormone, progesterone and luteinizing<u> hormone tend to decrease their levels at the end of the luteal phase, in the proximity of menstruation</u>.

The species that nowadays have the legless condition came from independent lineages such as scolecophidians, alethinophidians and legless lizards.
If 100,000 kJ of energy is available to the producers, 1000 energy is available to the secondary consumers in this food pyramid.
<h3>What is 10 law of energy flow explain?</h3>
According to ten per cent law only 10 per cent of the energy entering a certain trophic level of organisms is known for transfer to the next higher trophic level.
Thus, 1000 energy is available to the secondary consumers in this food pyramid.
