Explanation:
B) Molecules are moving from a higher concentration to a lower concentration
Water molecules from the more concentrated side, will flow into the less concentrated side til they equilibrate- at equilibrium both sides will have the same concentration of solute and water molecules.
In diffusion, small non-charged molecules can move from regions of high concentration to regions of low concentration. This occurs across the phospholipid bilayer, which acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic- this involves the movement of water molecules, gases or other small water-soluble compounds
.
In osmosis, molecules of water move across a semi permeable membrane, from regions of high concentration to regions of low concentration until an equilibrium is reached. This always occurs along the concentration gradient within the system.

Explanation:
Carbon cycle - It is defined as the process in which the carbon moves form the atmosphere into the living organism and the Earth and then back to the atmosphere. For example plants take carbon dioxide to prepare the food. Animals eat the plants and then carbon dioxide is stored in them or released in the form of carbon dioxide in the atmosphere.
Nitrogen cycle - It is defined as the process in which nitrogen is converted into different chemical forms as it circulates among terrestrial and marine ecosystem and the atmosphere. For example nitrogen present in the soil are absorbed by the plants through its roots which comes in the form of ions. Nitrogen is reduced to nitrite ions, when absorbed the plants. Further it becomes ammonium ions which can be incorporated into amino or nucleic acid.
Hydrological cycle - It is defined as the continuous movement of water below, above and on the earth. For example water at the Earth's surface evaporates into the atmosphere. Moisture moves around the earth with weather pattern, and rain and snow condenses from it.
