Net production efficiency (npe) is defined as the product of 100 and the quotient of net consumer productivity and assimilation. if the invertebrate primary consumers of an ecosystem exhibit a npe of about 20% and pass on about 1000 kcal/m2/yr to secondary consumers, what is the assimilation of the primary consumers?
a. 1000 kcal/m2/yrb. 2000 kcal/m2/yrc. 5000 kcal/m2/yr

The assimilation of the primary consumer is 5000 kcal/m2/yr, option C.

Explanation:

From the information in the question, the Net Production Efficiency, NPE can be calculated using 100Cp/AS.

Where CP is the consumer productivity and AS is the Assimilation.

Therefore, 20 = 100 x 1000/AS

AS = 100,000/20 = 5000 kcal/m2/yr. Option C.

answer; i believe that the correct answer is (light);

"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."
