Answer:
The answer is 'B'- There is already soil present.
Explanation:
One of the biggest difference between primary succession and secondary succession is that primary succession occurs where there is zero availability of soil. In case of secondary succession, an already established community gets hampered due to <em>man made</em> activities or natural disasters like <em>flood, rain</em>, etc.
Since there is soil present in his farmland and vegetation is also available, it is the process of secondary succession.

<span>Endoplasmic Reticulum
ER Golgi apparatus, because it packages proteins received from the ER cytoplasm </span>
<span>The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.<span>

Answer:
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
