The answer should be C. The image shows molecules of dye moving across a partially permeable membrane down a concentration gradient. A is used to describe movement of water molecules down a concentration gradient. B is often used to describe facilitated transport, aka protein mediated transport of substances down a concentration gradient. D would be referring to the movement of molecules against the concentration gradient which is not the case here.

Write an argumentative essay which says without photosynthesis there is no life​
AysviL [449]

Explanation:

you could include the points such as,

<em>-</em><em>-</em><em>></em><em> </em><em>photosynthesis</em><em> </em><em>produces </em><em>O2 </em><em>which </em><em>is </em><em>necessary</em><em> </em><em>for </em><em>respiration</em><em>.</em>

<em>-</em><em>-</em><em>></em><em>photosynthesis</em><em> </em><em>reduces </em><em>the </em><em>amount </em><em>of </em><em>CO2</em><em> </em><em>in </em><em>the </em><em>atmosphere</em><em> </em><em>as </em><em>it </em><em>uses</em><em> </em><em>it </em><em>up </em><em>in </em><em>the </em><em>reaction</em><em>. </em><em>this </em><em>controls </em><em>the </em><em>atmospheric</em><em> </em><em>rate </em><em>of </em><em>CO2</em><em> </em><em>and </em><em>reduced the</em><em> </em><em>greenhouse </em><em>effect.</em>

<em>-</em><em>-</em><em>></em><em> </em><em>plants </em><em>are </em><em>the </em><em>primary </em><em>producers </em><em>in </em><em>a </em><em>food </em><em>chain </em><em>and </em><em>so,</em><em> </em><em>photosynthesis</em><em> </em><em>plays </em><em>a </em><em>primary</em><em> </em><em>role </em><em>in </em><em>the </em><em>stability</em><em> </em><em>of </em><em>food </em><em>chains </em><em>as </em><em>they're </em><em>the </em><em>primary</em><em> </em><em>source </em><em>of </em><em>glucose </em><em>as </em><em>all </em><em>the </em><em>higher </em><em>consumption</em><em> </em><em>is </em><em>based </em><em>off </em><em>the </em><em>producer</em><em>.</em>

<em>-</em><em>-</em><em>></em><em> </em><em>virtually</em><em> </em><em>seeing,</em><em> </em><em>all </em><em>the </em><em>energy </em><em>within </em><em>the </em><em>biosphere </em><em>is </em><em>based </em><em>off </em><em>plants </em><em>that </em><em>depends</em><em> </em><em>on </em><em>photosynthesis</em><em>.</em>

<em>-</em><em>-</em><em>></em><em> </em><em> If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.</em>

there could be more but this is all I could think of.

hope it helps. :)
