Answer:

The answer is C serving size.

Explanation:

Looking at the serving size may be the best idea. If you see the serving size for example: 9 pieces, and that's 190 calories. You may not even want to eat 9 pieces. That's a lot. So if you eat only 3 like me you only have 63 1/3 calories now.

The point is: there is no point looking at the calories if you aren't going to eat the serving size amount.

Hope this helps. :)

What species concepts is not very useful in defining plant species because some plant groups readily hybridize with other plant
matrenka [14]

Answer:

The <u>biological species concept</u> is not very useful in defining plant species.

Explanation:

The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>

<em>Individuals belonging to a species cannot reproduce with members of other species. </em>

This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.

Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.

Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.

How are biotic factors in the marine ecosystem responsible for bringing carbon-dioxide into the ocean?
Wewaii [24]

Answer:

Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.

But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.  

Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
