niche >> an organism’s relationship or interaction with specific abiotic and biotic factors in its environment

commensalism >> a symbiotic interaction in which one organism benefits from the interaction, while the other remains unaffected

parasitism >> a symbiotic interaction in which one organism benefits from the interaction, but harms the other organism

Explanation:

A niche can be defined as the place of a given organism in a community and its ecological role within the ecosystem. Commensalism is an ecological relationship in which an organism/species benefits, while the other is neither harmed nor helped. An example of commensalism is the association between a frog that uses a tree as protection against predators. Mutualism is an ecological relationship in which both organisms/species benefit. An example of commensalism is the association between one bee and one flowering plant. Bees obtain nectar from the flower, while the flowering plant uses this mechanism to cross with other plants from the same species. Finally, parasitism is an ecological relationship in which an organism benefits, while the other organism is harmed. For example, a flea that lives on a dog is a parasite that exploits the host organism (dog) to obtain food.

answer: the answer is b

"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."
