Which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?

CaHeK987 [17]

The correct answer is: [D]:

___________________________________________________

→ " redwood tree forests " .

___________________________________________________

Note: Let us consider the other answer choices.

___________________________________________________

Choice: [A]: "garden flowering plants" ; is incorrect — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" — which means that they are "angiosperms" — Not "gymnosperms ".

→ Rule out: " Choice: [A] " .

__________________________________________________

Choice: [B]: " ferns and liverworts " ; is incorrect — since both ferns — as well as liverworts — are Not "gymnosperms ".

Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

→ Rule out: " Choice: [B] " .

___________________________________________________

Choice: [C]: " mosses and horsetails "; is incorrect ; since both mosses — as well as horsetails — are Not "gymnosperms ". Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — and Not by seed .].

→ Rule out: " Choice: [C] " .

__________________________________________________

Choice: [D]: " redwood tree forests " ;

— is the only answer choice provided that is a "gymnosperm".

Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."

Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are: "known to be important in maintaining the balance of carbon in an ecosystem."

__________________________________________________

→ As such, the correct answer is:

__________________________________________________

→ Answer choice: [D]: " redwood tree forests " .

Hope this helps!

kap26 [50]

Answer:

Georgia is the world's leading producer of Kaolin (china clay).

Explanation:

Kaolin or china clay contains the mineral kaolinite mainly. It also contains varying amounts of other minerals like muscovite, feldspar, quartz, etc. In order to prepare it for commercial use, the clay in its natural form is then chemically treated and washed with water to remove the other minerals.

Kaolin is extensively used in the ceramic industry and the paper-coating industry. The high fusion temperature and white burning characteristics are used in the ceramic industry for the manufacture of chinaware, porcelain, and refractories. In the paper-coating industry, the kaolin is mixed with the cellulose fiber in the paper sheet. This gives the paper its color, opacity, and printability. It is also used as a pigment additive in paints, as a filler in plastic and rubber compounds, and in pharmaceuticals.
