What effect would a drop in the size of the krill population have on the antarctic food web and why?

Krill is an zooplankton species that is extremely abundant in Antarctic water bodies. These zooplanktons feeds on phtoplanktons present in the Antarctic water bodies. Therefore, in antarctic food chain Krill belong to primary consumer trophic level. In Antarctic they are source of food for seals, penguins, whales, fishes and birds. These are included in secondary, tertiary and quaternary trophic levels of the food chain. The drop in the size of the krill population will result in limitation of populations of species at higher trophic levels. As, many food chains are interconnected to form a food web therefore, the drop in size of Krill in one food chain will also affect the overall food web of Antarctica.

i think the answer is gold im not entirely sure

"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."
