Answer:
The correct answer is osmosis is the movement of water across the membrane;diffusion is the movement of molecules from a higher to lower concentration with or without the presence of membrane.
Explanation:
Diffusion and osmosis are the two most important process of passive transport.Both diffusion and osmosis helps in the movement of water molecules from high water concentration region to region of low water concentration until equilibrium in both sides is reached.
Osmosis needs the presence of a semipermeable membrane to occur.

To measure cross-linking amino acids in a collagen hydrolyzate using a conventional amino acid analyzer with ninhydrin detection, the bulk amino acids must be largely removed to avoid plugging the reaction coil. Tissue is thoroughly reacted with sodium borohydride to convert all intermediate cross-linking residues to their reduced, acid-stable forms. More vigorous reduction conditions may be used than when preparing profiles of tritium-labeled cross-links using NaB3H4<span> and direct amino acid analysis. </span>
Between every food chain from one animal to another there is 90% energy loss so if a herbivore eats a plant, it will only get 10 joules of energy. and if a carnivore eats the herbivore then it will only get 1 joules of energy. so in every food eaten, there is 90% energy loss.
