The growth of mosses and lichens on a bare volcanic region helps prepare the area for the next stages of succession. How do mosses and lichens most contribute to this process? Asap

A.
They poison populations of primary consumers.

B.
They build up soil deposits on the rocky ground.

C.
They neutralize deposits of extreme acids in the rocks.

D.
They increase the amount of oxygen in the surrounding air.

The correct answer is - B. they build up soil deposits on the rocky ground.

Explanation:

Lichens and mosses are known as the pioneer species as they prepare the particular region for the next stages of succession on the bare volcanic region. Lichens and mosses grow on the bare rocks and secrete acids to break the rocks and start soil production.

The soil deposits produced by breaking the volcanic rocks by secreting acids from mosses and lichens. Even after dying these species leads to thickening of the soil and increase organic matter for the next stages to grow.

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.

"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."
